One day, one of them became curious enough to ask Stanley why he exercised all day. Stanley said, "Look, pal, only one sperm gets a woman pregnant and when the right time comes I'm going to be that one."

A few days later, they all felt themselves getting hotter and hotter, and they knew that it was getting to be their time to go. They were released abruptly and, sure enough, there was Stanley swimming far ahead of all the others. All of a sudden, Stanley stopped, turned around, and began to swim back with all of his might. "Go back! Go back!", he screamed. "It's a blow job!"
