Not really good, but kind of funny.
I "beat"
Muscles (a young weight lifter I work with) in a handgrip contest. We had two people bet on "Gorilla Hands" (that's me) and six people bet on
Muscles (he is about twenty six, cute, ginger, solid, not smart).
I was about to call it quits (I am a bit too old for this shit, but only one guy knows how old I really am. He bet on my winning) or ask for a draw, when Muscles brought his other hand into the contest to "cheat." At that point, I simply placed one finger of my other hand on a pressure point, practically paralyzing his hand, which allowed me to bend it backwards/sideways between his middle and ring fingers. I knew then, it was over, since he cheated, and I watched him grimace and try to be tough for a few seconds more. A tiny bit more pressure and he gave up, freaked out. He asked what the hell I had done to him. I just said, "You tried to cheat. I cheated back. You lose."
He said, "No, you made my hand die, WTF did you do to me? It still hurts." I just reminded him that he had tried to cheat, by bringing in his other hand to win. I just touched a nerve and made his hand weak. I asked if he wanted to try again, without cheating. He said, "FUCK NO! You win."
Never try to cheat on someone who knows more tricks than you do.
