Two storks are sitting in their nest: a father stork and baby stork. The baby stork is crying and crying and father stork is trying to calm him. "Don't worry, son. Your mother will come back. She's only bringing people babies 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 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. Just scaring the hell out of college students!"
