Joke from JokesArena.com funny stuff
Once upon a time in a place where little sperms grow, there was a super jock sperm who spent all his time working out. He did things like lifting weights and running, his most important duty. All the other sperm were very curious about his pastimes.
"Why do you keep working out all the time," they asked.
"Well," he said, "Of all us sperms, only one of us is going to make it to the egg. And that is going to be me." Well, the other sperms just floated around waiting for the day to cum (pardon the expression). And it did, and they were off! All those sperms racing along and far out in front of them was the super jock sperm, racing so fast and so hard (ha HA ) that they couldn't see him any more, but they still kept cumming.
Alas, then, away in the distance, they heard a loud piercing scream. They still kept cumming though.
And then very shortly the super sperm appeared, screaming with all his might, "Go back, Go Back! IT'S A BLOW JOB!"
