A little girl walked into the bathroom, saw her father in the shower, and ran to her mother screaming, "Mommy, Mommy! Daddy has a big ugly worm hanging out of his wee-wee!"
"That isn't a worm, sweetheart," said her mother reassuringly. "That's part of your daddy's body, and a very important part. If your daddy didn't have one of those, you wouldn't be here."
Pausing thoughtfully, the woman added, "And come to think of it,...neither would I."
