Tennis Arm

The unfornutate condition in which one arm is larger and more heavily muscled than the other. Men claim that this is the result of playing a lot of tennis, but generally the real culprit is vigorous masturbation.

Mom: "if Timmy doesn't stop playing so much Tennis he'll wind up with Tennis Arm"
Dad: "...and if he doesn't start putting a sock on it we're going to have to throw away his bed sheets!"
