After purchasing the Sonar Collections Dock while playing as Michael (available for purcahse after completing "The Merryweather Heist" story mission for $250,000) you can start collecting nuclear waste with the submarine. After purchasing the docks you will get a new app called "Trackify" that provides a radar that points to the next collectible. You receive $32,000 per barrel of nuclear waste collected, and a $250,000 bonus after finding the final one. Collect all of them to get the "Waste Management" achievement/trophy:
View the following video to see the location of every nuclear waste barrel:
When doing these for the trophy/achievement and 100%, play as Franklin so you can trigger his special ability to slow down time while driving (which is very helpful for lots of the Stunt Jumps). The recommended vehicle for the Monster Stunts is the Pegassi Bati 801 motorbike as you can do pretty much every stunt with it. However, some stunts are easier to do with a sports car.
When stuck at a stunt, use the same type of vehicle that is shown in the video. You must always land in a specific area, or even a specific spot to complete the Stunt Jump. If driving too fast or too slow, you might miss the target area and the stunt will fail. A neat trick to use is to quick save the game before every stunt jump. After loading the saved game, you will be sitting in your car or bike at the exact same spot where you saved the game. This allows you to never lose any progress if you die or destroy your vehicle.
Steal an armored truck and escape from police, then drive the truck back to the garage without opening it to take the contents. Once you park it in your garage, save the game and then load your save. The truck should be in your garage and you can blow open the back doors to retrieve the contents. Then, simply load your save again and repeat the process as often as desired as long as you leave the truck in the garage.
For a quick $5,000, watch for armored cars to appear. They are marked by blue dots on the map. Simply kill the guard before he enters the armored car. If you have to open the armored car to get the money, drive into water to pop open the rear doors.
Keep an ey on rivalries between large corporations; Lester will give you information about which companies are rivals. Since destroying the assets of a corporation will cause their rival's stock to rise, use it to your advantage by first investing in the rival's stock. For instance, destroying planes belonging to AirEmu at the Los Santos Airport will cause stocks in FlyUS to rise. The same can be done with oil derricks belonging to RonOil or LTDOil. When a mission objective includes destroying a corporation's asset or reputation, make sure you first invest in their competitor.
Once you have two playable characters, go to Paleto Bay and swim into the ocean. Dive at the indicated location and collect the $12,000 from the crashed airplane. Once done, switch characters and switch back to your original character. This will respawn the underwater money, as well as restore your oxygen. Collect the money again and repeat the process.
Take a sub and search the seafloor of the western coasts until you find a structure that resembles a sub, only much larger. You can find an RPG on the seafloor next to it, and a briefcase containing $25,000 dollars laying on top next to the open hatch.
Go to the location indicated by the video in Rockford Hills to find an exotic/super car that always spawns in this location. The Truffade Adder (Bugatti Veyron) super car is the most frequent to spawn at this location, and also the fastest car in GTA V.
The same cul-de-sac of Grove Street also has a presence in Los Santos, located not too far from Franklin's house and features graffiti in the green of CJ's old gang. However, a different gang occupies this version of the street.
Look in Franklin's bedroom to see a Mad Dog poster and an album by OG Loc on the floor.
During the "Urban Safari" mission, Lamar, Franklin, and Trevor will enter the Grove Street area for a drug deal. The house that they go to belongs to CJ's brother, Sweet Johnson.
You can see the "WELCOME BACK. We missed you last time." graffiti message that welcomes players back to the sandbox of San Andreas upon leaving for Liberty City in GTA IV.
Go to the juice stand with a large orange ball sign on its roof at the highest point of one of the roads in Vinewood Hills, then climb on top of the roof and punch or kick the ball off its base to send it rolling down the hill.
Elysian Fields Co., the corrupt construction company entangled in the highway conspiracy in L.A. Noire, appears in Los Santos. L.A. Noire obviously takes place in Los Angeles, and GTA 5's Los Santos is a fictionalized version of L.A.
There are posts by Brucie Kibbutz on Bleeper. He has seemingly done well for himself, now owning a website as a well-respected "fitness expert" and "lifestyle guru!".
Franklin can help Packie McReary during a heist,. He becomes a crew member afterward.
Johnny Klebitz from The Lost And Damned accuses Trevor of sleeping with his girlfriend, Ashley.

While in Michael's home, zoom into Jimmy when he is using his laptop at the dinner table. He will be viewing the LifeInvader profile for Niko Bellic
Franklin has a friend on his LifeInvader page named "Nicholas Bell", a reference to "Niko Bellic" from GTA IV.
Go to Michael's home and zoom into Jimmy when he is using his laptop at the dinner table to see him viewing the LifeInvader profile for Niko Bellic.
One of the movies at the cinema shows the beating heart inside the Happiness Island statue that could be seen in GTA IV.
Near the end of the "Monkey Business" mission, the gentleman in the suit with glasses who works for the lab that you are stealing from tells the guards to detain the FIB agent, who shoots himself in the leg to cover for his friends, is the same person known as Edward T. Fortune that gives Nikko the information he seeks in return for him doing missions for the United Liberty Paper in Grand Theft Auto IV.
During the "The Paleto Score" mission, the four characters will discuss their first big score. If you selected Patrick "Packie" McReary, he will talk about his first big score being the Bank of Liberty City and say something similar to "...and my friend Niko who is probably dead."

Listen for a radio commercial that mentions people of Los Santos are taking drugs like crazy. They then start to list some drugs, and one of them is called Zombix, a reference to the Zombrex drug in the Dead Rising series.
Jump out of either the submarine or Zodiak Boat (Dinghy) into water toautomatically be wearing the scuba gear. Note that you can't carry scuba gear as an item. Go to these locations to find the submarine and Zodiak Boat (Dinghy):
Submarine When you buy the "Sonar Collections Dock" property there will be a submarine that spawns at that dock. Also, after completing "The Merryweather Heist" (Offshore Option) mission, a submarine will start spawning at Sandy Shores Airfield. Pick it up using a Cargobob air transport plane (press Right on the D-pad), and then drop it in the ocean where you want to use it.
Zodiak Boat (Dinghy) At the west side of Elysian Island is a Dinghy at the Port of Los Santos. You can find another one by going to Miriam Turner Overpass, and searching next to the barge. There is also one on the southwest side of the Post Op depository.
Press Y when prompted at the bottom right corner during character creation to have a "Special Dad" replace your currently displayed father, John Marston from Red Dead Redemption. Note: This may require a saved game file from Red Dead Redemption.
A great defense against cash-drain during money farming is to stay altogether outside the open world and jump from Job to Job as fast as possible. Dying during Jobs only costs you hospital fees (you won't drop your money like in free mode), and since Jobs are already the best way to farm money early on, you'll get rich simply following the flow of a group Playlist while farming.

Toward the north side of the map is a diner called Up-n-Atom that has a statue of a rocket positioned next to it. The color scheme resembles the one used for the Rocket Souvenir item in Fall Out: New Vegas. If you get near the rocket, you'll hear the sound of radiation, similar to the reader in the Fallout series.
At the Astro movie theatre is a small reference to "Die Hard," the 90's movie series that stared non other than Bruce Willis. This can also be seen throughout the city of San Andreas on posters and radio broadcast!
With a fast car and with your special bar filled, go to the military base as Franklin and drive at the front gate at full speed. Activate his driving ability just before you break through the gate arm. Make your first right and then a quick left and drive up the runway to the jet with his special on as long as possible. Usually you will reach the jet before the alarm even goes off. This works 9/10 times once you memorize the location, and if you're not unlucky enough for a tank to happen to be right next to the jet.
Additionally, if you land the plane in the hangar by Trevor's house, (not the one you buy), try to pull all the way into the back of the hangar and quick save. Now load the game again and you should be inside your jet plane AND a second perfectly undamaged one will be waiting for you at the entrance of the hangar as well.
In Chiliad Mountain State Wilderness near the Fort Zancudo military base you will sometimes come across a random event where you will find a clearing in the desert with some bullet-ridden trucks and dead/dying drug dealers. Further down a hill you will find two more dying drug dealers and a silver case full of cash. This is identical to the scene where Josh Brolin's character finds a case full of money in the movie No Country For Old Men. Note: If you do not get the random event to happen, quick save the game, reload it, and then return to the location again. Repeat this until the random event occurs.
To use Franklins special ability with any character, just hold open the radio wheel while drivng. Note that time will be slower than when using Franklins ability, although all driving controls will still be functional.
To travel to a location across the map quickly, choose a race that is nearby to where you want to go. Then, go to the race, enter the lobby, and drop out of it. You will then spawn at the start of the race location in free roam mode.
Note: You will need a decent amount of cash to fully upgrade a vehicle. After completing the "Father/Son" story mission to unlock Los Santos Customs (car repair shop), open the internet browser on your in-game cell phone and go to "southernsanandreassuperautos.com". Purchase the Weeny Issi for $18,000 and retrieve it from your garage. Once done, go to Los Santos Customs and buy the following upgrades, then leave the shop to unlock the achievement:

Play as Franklin and start the side-mission where you meet up with Beverly (the photographer). He will tell you that some people want to make a reality show about what he does as a celebrity photographer. On the wall next to where Beverly is you can see a text that reads "Karma: It's A Chameleon", a reference to the band Culture Club and their 1983 single Kharma Chameleon.
Go to go to "junkenergydrink.com/page5" via the internet browser on your in-game cell phone to see the locations of all 50 stunt jumps. Completing all 50 stunt jumps will unock the "Show Off" achievement./trophy Playing as Franklin is recommended while attempting these since you can trigger his special ability to slow down time while driving. Also recommended is the Pegassi Bati 801 motorbike as it is capable of almost every stunt, although certain stunts are easier to do with a sports car.
View the following video to see how to perform each stunt and which vehicle you should try if you are having trouble:
Towards the end of a certain mission, Franklin and Michael tie the back of their stolen vehicle to the underside pole of a cheating tennis coaches house. Michael then uses the vehicle to pull the house down just like Riggs did in Lethal Weapon 2.
Note: Some of these hints may only work on the unpatched version of the game.
Create an invite only game session, go to any store, and rob it. Punch the clerk so they all run off, then take all the money in the cash register. After that, enter the Start menu and go to Xbox Live Marketplace as if you were going to buy in-game money. Once Xbox Live Marketplace loads, exit it and you will spawn back in the same store at the exact same spot, except the world will have refreshed. You can then attack the clerk again and take the money from the cash register. Repeat this process as many times as desired. You can get about $100K an hour using this glitch.
To make easy money at the start of GTA Online without alerting the police, steal a good common car in Vinewood. Once done, go to a Los Santos Customs car shop. You can sell stolen cars to car shops, although most car shops will not accept luxury sports carst. You will get about $9,000 to $10,000 for a good common car that does not have significant damage. After earning some money, deposit it at an ATM to avoid potentially losing it to other players or if you die. Once you are satisfied, buy some body armor and weapon customization to do heists and robberies to earn more money. It is recommended you buy a silencer for your weapon when you have enough money so you can avoid heat from the cops.
When you reach Level 45, the "Mixed Up With Coke" mission will be unlocked. The earnings for completing this mission are $18,000 and 3,500 RP. It can take more than 15 minutes to complete the mission the first few times, but once you figure it out, it can be completed with three other players in less than two minutes. Note: One player will need to be at Level 45 to access the mission, as well as one player at Level 19 or higher and two players at Level 9 or higher to do the mission.
When you reach Level 75, the "Rooftop Rumble" mission will be unlocked from a guy named Martin Madrazo (leader of a Mexican narcotic gang in the Los Santos area). To complete the mission, you just have to kill five people. It is possible to earn up to $2 million and 400K RP per hour by repeatedly completing the mission. Note: You can also do the mission if you are at a lower level and get invited by someone at Level 75 or higher. If you are at a lower level, make sure to use sticky bombs instead of the grenade launcher, and kill any survivors with a rifle.
The "Rooftop Rumble" mission will be unlocked when you get to Rank 75, from a guy named Martin Madrazo (he leads a Mexican narcotic gang in the Los Santos area). To complete the mission, you must kill five people. It is possible to earn up to $2 million and 400K RP per hour by continuing to complete the mission. Note: You can also do the mission if you are at a lower rank and get invited by someone at Rank 75 or higher. If you are at a lower rank, make sure to use sticky bombs instead of the grenade launcher, and kill any survivors with a rifle.
Drive a vehicle to Los Santos International Airport and drive through the gates to reach the runway. Once done, immediately look for a jet to hijack. Your wanted level will increase while on the runway so you must find and steal the jet fast.
Note: You may miss the "Altruist Acolyte" achievement if you deliver all people from random events to their target destination instead of the Altruist Cult. Only Trevor can deliver people to the Altruist Cult and it will not work with the other two characters. You will have several opportunities to get this achievement, which can be unlocked during any of the four random hitchhiker events. These events will sometimes show up as a blue dot on your mini-map when they are nearby. One hitchhiker is located on the street at the southern foot of Mount Chiliad. The random events do not always show up, but have fixed locations. If you can't find the hitchhiker, just drive in another direction for a quarter mile, and then go back to the location. Eventually the event will spawn if you keep doing this. Drive to the blue dot on the map and wait until the hitchhiker gets into your car. Instead of going to the target destination, drive to the Altruist Cult. It is marked with a big "A" on your map, on the west side of Mount Chiliad. This symbol will only show up once the hitchhiker is in the car. Deliver the person to the cannibals of the cult to get the "Altruist Acolyte" achievement and some money.
At least two people are required for this, with one of them being able to get the mission from Lester called "Cops Capacity". In this mission you will get a Vapid Dominator with bulletproof tires. Complete the objective until you must drive to his compound to end the mission. Allow the other player to get there alone, while you remain seated in the Dominator. When the mission ends and the game resumes, you will still be in the Dominator. Drive it to a garage and place a tracker and insurance on the car and it is yours, with a free bulletproof tires upgrade.
Steal a taxi and start driving it around until you are assigned a job by the dispatch operator. Accept the job and follow the GPS path to reach the waiting customer. After picking up the customer, take a roundabout route to the requested destination. Your passenger will have to pay for the ride according to the distance driven, even if the fare winds up in excess of $1000 because you went joyriding. This is an easy way to make money near the beginning of the game.
Obtain a fighter jet from Ford Zancudo to unlock the ability to complete all 15 Knife Flight aerial challenges with it. You can also use a stunt airplane (they occasionally land at the airport in the desert). Visit the Flight School at Los Santos Airport to learn how Knife Flights work, and maxxing out the "Flying" attribute for one of your characters to have more control over the aircraft is recommended. If your aircraft gets badly damaged, quick save the game, and immediately reload the game to repair it. It is also recommended you quick save the game before attempting the more challenging Knife Flight stunts.
View the following video to see the location of every Knife Flight challenge:
Unlike other GTA V collectibles, there are no special requirements or side missions necessary to make letter scraps appear--they can be collected at any time, even at the start of the story, and with any character. Note that some letter scraps require a helicopter to be obtained. Once all 50 letter scraps are collected, go to the green "Killer" question mark while playing as Franklin to meet Leonora Johnson's killer (Dreyfuss). You must kill him to get the "A Mystery, Solved" achievement/trophy.
View the following video to see the location of all 50 letter scraps in the game:
This glitch allows you to duplicate another player's vehicle, which you can then either keep or sell . First, request a job from Gerald while you are in another player's vehicle. Use the other player's vehicle for the mission, and make sure you are driving it when the mission ends. You should then enter free roam mode, and still be in the vehicle. You can then go to Los Santos Customs and try selling the vehicle. If you cannot sell it at that point, add a tracker to it and try going back later to sell it. If you want to keep it, add a tracker to it and insure it.
In Franklin's bookshelves there's a book titled "Red Dead", authored by J. Marston. You may recall that in Red Dead Redemption Jack Marston (John Marston's son) mentions his plan to write a book about his father and the Wild West.
Two locations called "Armadillo Ave" and "Cholla Springs Ave" within the rural area of the map are a reference to Red Dead Redemption's Armadillo Town and the surrounding region of Cholla Springs.
A farm identical to John Marston's homestead can be found south of the prison.
For this achievement you must get one gold medal for each type of activity, and there are six hobbies and pastimes-- Shooting Range, Flight School, Offroad Race, Sea Race, Street Race, and Triathlon) in GTA 5. All of them unlock by completing story missions. The shooting range is the most difficult to get a gold medal in as you will have to get a certain number of points within a time limit. Shoot fast and always hit the yellow center area of the targets. In the flight school, simply beat the time limit in the first tutorial. In races and triathlon, you must finish first to get a gold medal. Street races become available by completing Hao's side mission. However, the mission requires you to get a gold medal in a street race. Therefore, don't have to complete any further races to get the "Multi-Disciplined" achievement. Note: Hao's side mission only becomes available from 8 p.m. to 5 a.m. while playing as Franklin, and is shown as a question mark on the map. For the other hobbies and pastimes, you can select any desired character.
The Epsilon quest line is the longest in the game and becomes available when you unlock Michael as a playable character. To trigger the missions you will have to play as Michael and need to have at least $90,500 with Michael as certain donations have to be made and you must buy an expensive outfit. However, completing all of "The Truth" Epsilon missions can earn you up to $2,100,000. In the last quest, you have the opportunity to earn $2.1 million and a gold medal.

It disappears if you get too close, so use the scope on your sniper rifle to get a good view. It is likely the ghost is Jolene Cranley-Evans, and her husband is suspected of pushing her off the cliff. Her husband was Jock Cranley, who moved to Los Santos to become a famous stuntman and is currently running for senator of San Andreas. He is referenced during one of Trevor's Strangers and Freaks missions. During the mission, you steal celebrity items for a man named Nigel. When Trevor encounters Nigel, Nigel mistakes him for Jock, and continues to do so until Nigel's missions with Trevor end.
You can find secret messages on the Special Edition version of the paper pack-in GTA 5 map, which can be seen only with a UV (black) light. The lengthiest message reads:
T.P.E - Trevor Philips Enterprises. Weaponry, narcotics, intimidation and casual wear. Lago Zan Cudo. Great Ocean, Highway north, through north Chumash, 0.5 miles past Raton Canyon. When guard rail ends, follow the dirt road down the docks. Bring $500,000 cash.
Going to the location indicated by the secret message takes the player to a remote dock available for sale. The Minisub is stored there, and offshore a number of Nuclear Waste barrels can be gathered for cash. Other messages can be found on other parts of the map referencing aliens and the Buzzer and Lazer aircraft. Going to the location indicated by the flying saucer reveals a very well concealed Spaceship Part.
While a mission is active, go to the gun shop and purchase everyone upgrade for every available weapon and some grenade. After obtaining all of the upgrades, leave the gun shop, and use one of the grenades to kill yourself. This will cause the mission to fail and you will start the mission over. Once the mission restarts, you will have all of your money back from the purchases in the gun shop. Return to the gun store, and all the weapon upgrades will still have a checkmark. Repeat this process when new weapons become available.
Note: Playing as Trevor is required. Complete the "Mr. Philips" story mission to have an orange question mark appear on the map at the northeast end of the desert. Go there to speak with Maude and unlock the bail bond side missions, then return to your house, take a nap, and you should receive an e-mail with details about your target. You have to go east to the "Davis Quartz" area. Once you find the target, quickly shoot the tires of his car, and when he tries to run away, hurt him, but do not kill him. You can hit him with your car to hurt him, but not too hard. You can also use the stun gun (can be bought at the gun shop). He will then automaticallyenter your car. Once done, drive back to Maude. After turning over the bail bond target to Maude, you will unlock the "Wanted: Alive Or Alive" achievement. Note: You can miss this achievement if you kill all bail bond targets instead of bringing them in alive. There are four bail bond targets, so you will have four opportunities to get this achievement.
Since sharks spawn at random in deep water, head out into the ocean with a boat or jet ski and watch the mini-map until it turns completely dark blue. Dive around until you see a red dot on the radar, indicating a shark, then jump into the water and wait until it kills you. It may take some time if the shark does not see you right away. After getting killed by the shark you will get the "Out Of Your Depth" hint. If the shark attacks and destrosy the boat or jet ski you will also unlock the achievement.
Starting the "Far Out" side mission, which becomes available after completing the "Fame Or Shame" story mission, will make spaceship parts appear. The spaceship parts are small, glowing objects that emit a vibration sound when you approach them, and some require a helicopter to obtain. Collect all 50 spaceship parts and return them to Omega to earn the "From Beyond The Stars" achievement/trophy.
View the following video to see the location of all 50 spaceship part locations:
Obtain a Maverick helicopter from the South Los Santos hospital helipad to perform these aerial challenges. Maxing out the "Flying" attribute on a character is recommended so complete the Flight School at Los Santos Airport before attempting the harder challenges. To complete a challenge you cannot touch the ground or any part of the bridge at all while flying under it. Completing all 50 challenges will unlock the "Close Shave" achievement/trophy.
View the following video to see all 50 bridge locations:
Note: May only work on the unpatched version of the game. Go into the restricted area at the Los Santos International Airport through the fence (jump it or drive through it), near the flight school to find three helicopters. Use the helicopters to escape the police after robbing stores, but make sure the helicopter is not parked where the cashier can shoot you. Robbing and escaping the cops will also earn you easy XP. You will usually get from $1,000 to $8,000 for each robbery.
The Canins Mesa is unique off-road vehicle that wasn't meant to be owned in the game. To obtain it, play the "The Wrap Up" mission where you will be given access to a Canins Mesa to escape a shootout. However, do not drive it on the road. Take a left down the hill to another road. There will be a helicopter chasing you but you can outrun it. You must reach Michael's four vehicle garage and park the Canins Mesa in the garage, then use a different vehicle to complete "The Wrap Up" mission. Once the Canins Mesa has been saved, you can also modify it.
While offline, play the "Prologue" mission from the "Missions" menu. Proceed until you exit the vault heist and the police arrive. Pause game play, then have a friend invite you into a Grand Theft Online multiplayer session. North Yankton will now appear on the Grand Theft Auto Online map, floating over the southeast area of the map. You can use a helicopter to reach it.
There are stars on the sidewalk just in front of the Chinese theatre (west of where Michael can purchase the Doppler Cinema in Downtown Vinewood). One of them reads Candy Suxxx on it, the popular porn star from GTA: Vice City.
The main property management mission that becomes availalbe after Michael buys the Doppler Cinema includes using a plane to drop flyers from above to advertise the theatre, a task similar to a mission Tommy Vercetti had to complete in GTA: Vice City.
Using a mask before committing a crime will allow you to easily lose one star from your wanted level once the police start chasing you. Wait until the cops cannot see you after the crime has been committed and they are pursuing you, then take off the mask. One wanted level star should immediately disappear. However, it will not have an effect if you only have one wanted level star.
After unlocking Trevor by completing the "Mr. Philips" story mission, call the other two playable characters with your in-game cell phone and pick them up with a four door car. Go to the Los Santos International Airport at the southern end of the map. Entering the airfield will give you an instant 3-star wanted level, so drive from one end of the airport to the other for three minutes while making sure not to lose the cops to get the "Three Man Army" achievement. To make this less difficult, upgrade your car with the bullet proof tires from the car repair shop. Note: It is possible to miss this achievement depending on the game ending you obtain, so make sure to get it before the last five story missions.
To farm jobs repeatedly (even after the latest title update), hit Like on the mission after completing it and have everyone in the game hit RT (360) or R2 (PS3). The words Restart will appear in the final column befroe the mission begins again. Players can do this infinitely, getting money and RP each time. This works better with Jobs that can be repeated quickly, such as Violent Duct Job. Note that if you exit the mission entirely, you may be locked out of it for a duration of time, preventing you from restarting it. Make sure to only quit out of the mission after you are satisfied with the money you have made thus far.
Activate the following cheats by entering the corresponding codes. Note: Cheats cannot be saved, and must be entered manually each time. Cheats disable achievements for the current game session, so quick save your game before using cheat codes:
Go to the location inidcated by the video below and enter the cave, then dive to the bottom to get a grenade launcher. Swim back to the surface, save the game, and reload the saved game. The grenade launcher will have respawned. Repeat this process as many times as desired.
Reach the waypoint indicated on the video by swimming or take a boat or jet ski. Before diving to the treasure box on the ocean floor, quick save the game in case you drown. There is a treasure box to the right of the sunken plane wing in this area that earns you $12,000 when collected. Grab the treasure box and swim back up to the surface. Save the game again and reload the saved game. The treasure box will have respawned. Repeat this process as many times as desired to get an infinite amount of money. Note: It may be hard to locate the treasure box at first. The closer you get to the treasure box, the more shiny and obvious it will become.
During the mission where you chase two targets through the Cassidy Creek forest in a helicopter, use the rifle equipped with a thermal scope and aim down to the right and search for a larger than human thermal signature, which will almost immediately disappear. You can turn off the scope to get a blurrier real view of it.
Buy the Downtown Cab Co. to eventually get a mission to pick up and drop off a Korean pop singer called Kwack. He will complain that everyone calls him Quack. He will also say he made millions off a music video of him and a couple strippers dancing around doing jockey like dance moves around a horse--a clear reference to the Gangnam Style song by PSY.
