Three out of Four
Three of the tennis foursome head for the showers after the match. The fourth one just gets into his car and goes home. This happens every week–the same three shower, number four, doesn’t.
Finally, one guy asks him why he doesn’t shower after playing tennis; he is, after all, just as hot and sweaty as the other three.
“To tell you the truth,” he says, “I’m kind of shy about being naked in front of other guys. To be perfectly blunt, I’m not all that well endowed.”
“Well,” his friend says, “does it work all right?”
“As far as that goes, sure, it works all right. I’ve been getting laid on a daily basis for almost 20 years. It never fails to perform.”
“How’d you like to trade it for one that looks good in the showers?”
