To win a Fist Fighters match without throwing a single punch, go to Twinblade's bandit camp. Get as many bandits to follow you as you desired. Join the Fist Fighters gang and the bandits will slice them to pieces for you. Note: This will not work on the final Fist Fighters gang, because bandits cannot teleport. Also, mercenaries won't fight for you; only the bandits will.
