On preparing to return home from an out of town trip, a man got a small puppy as a present for his son. Not having time to get the paperwork to take the puppy on board, the man just hid the pup down the front of his pants and snuck him on board the airplane.
About 30 minutes into the trip, a stewardess noticed the man shaking and quivering. "Are you okay, sir?" asked the stewardess "Yes, I'm fine," said the man.
Later, the stewardess noticed the man moaning and shaking again. "Are you sure you're alright sir?" "Yes," said the man, "but I have a confession to make. I didn't have time to get the paperwork to bring a puppy on board, so I hid him down the front of my pants."
"What's wrong?" asked the stewardess. "Is he not housebroken?"
"No, that's not the problem. The problem is he's not weaned yet!"
