The fit sperm cell
Once upon a time there was this sperm called Brian. Brian
was a very health conscious sperm who spent all his time
doing push-ups, sit-ups, somersaults and generally charging
around the testicle being fit, while all the other sperms
just slobbed about the place doing nothing. One day, one
of the other sperms roused himself long enough to become
curious, and asked Brian why he exercised all day. Brian
said Look pal, only one sperm gets to make a woman
pregnant, and when the right time comes, I'm gonna
be the 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. Then they were abruptly released
and sure enough, there was Brian swimming far ahead of all
the others. All of a sudden Brian stopped, turned round
and began to swim back with all his might. Go back!
Go back! he screamed, It's a blow job!
