Storks

Two storks are sitting in their nest: a father stork and
ababy stork.  The baby stork is crying and crying and the
father stork is trying to calm him. "Don't worry, son.
Your mother will come back.  She's only bringing babies to
and making them happy." 

The next night, it's father's turn to do the job.  Mother
and son are sitting in the nest, the baby stork is crying,
and the mother is saying "Son, your father will be back as
soon as possible, but now he's bringing joy to new mommies
and daddies."

A few days later, the stork's parents are desperate: their
son is absent from the nest all night!  Shortly before dawn,
he returns and the parents ask him where he's been all night. 

The baby stork says,
"Nowhere. I was just scaring the shit out of college students!"
