The wrestler was about to enter the match, and the coach gives him some last minute advice.
"Son....whatever you do, do not let yer opponent get you in the pretzel hold. If you do, it's all over."
The match begins, and soon enough, he's in the pretzel hold. They're a rumblin' and a tumblin', still in the pretzel hold.
All of a sudden the wrestler sees a set of balls right in front of his face. In desperation, he bites them.
The wrestler not only gets outta the hold, but he slams his opponent to the turf, pins him, and wins!!!
After the match coach asks "Son, what happened??!! After you were in the pretzel hold, I thought you were finished!!"
"Well coach," the wrestler said, "you just wouldn't believe how strong you can get after you bite yer own balls."
