One day there were two boys playing by a stream. One
of the young boys was lingering over by a bush. The other boy
couldn't figure out why his friend was at the bush so long, so he
walked over to the bush, and to his astonishment saw a woman
bathing naked in the stream. All of a sudden the second boy took off
running.

The first boy couldn't understand why his friend ran away so abruptly, so
he took off after him. When he finally caught up to
him, he asked why he ran away.

The boy said to his friend, "My mom told me if I ever saw a naked
lady I would turn to stone, and I felt something getting hard, so
I ran."
