There is an international wrestling match between the U.S.A. and Russia. The American coach is talking to his star wrestler before the game and warns him about a new move the Russians have called the 'Russian Corkscrew'. He tells the boy that no matter what not to let him get that hold.
The match begins and both sides are very even. At the last 30 seconds, the Russian pulls the 'Russian Corkscrew' on the American.
The coach is very angry and leaves for the locker room. He starts slamming lockers and throwing chairs when suddenly he hears this weird sound coming from the gymnasium. LIstening in on it, he hears people chanting, "U.S.A.! U.S.A.! U.S.A.!"
Surprised, he walks out onto the gymnasium to see the Russian passed out on the mat and the ref holding the American's hand up in the air in victory.
After the match he pulls the boy aside and asked "How did you do it? How did you get out of the 'Russian Corkscrew'?"
The boy replied, "I was laying on the mat and out of the corner of my eye I saw these testicles hanging there. I thought what have I got to lose so I bit down on them. Oh man, you never know your own strength till you bite your own balls!"
