To perform this trick, you will need a TV with the Cooking, Fishing, or Gardening channels and a video game system. Have one Sim watch TV on any of those channels to start earning skill points. Then, have a second Sim start playing video games on that TV. The first Sim will continue to earn skill points. Allow the Sim to sit their until they move on their own. The skill meter will continue to stay above their head. If you repeat the steps until the Cooking, Fishing, and Gardening channels have been viewed, the Sim will be learning three skills at once.
