Two little boys are in the woods playing catch with a football. One kid says go deep. He tosses the ball out of the kids reach and it lands in bushes.
So the the kid goes in the bushes to get the football. 5 minutes go by and then 10. The kid gets worried and goes in after him. He finds his friend spying on a girl skinny dipping. They stare for a while then one kid runs away.
So the other kid caught up with him and asked him why he ran. He said my mom told me I would turn to stone if I saw a naked woman. I felt something getting hard so I ran!
