The man was in a hurry to board his flight and had no time to complete the paperwork for his puppy. He stashed the dog inside the front of his pants and sneaked onto the plane. About thirty minutes into the flight, a flight attendant noticed him squirming in his seat.
"Are you all right, sir?" she asked.
"Yes, I'm fine," the man replied.
Later, she noticed him moving strangely again.
"Are you sure you're okay?"
"Yes," the man said, "but I have a confession. I didn't have time for the paperwork, so I hid my puppy in my pants."
"I see," said the flight attendant. "Well, as long as he's housebroken, it should be fine."
"Oh, he's housebroken," the man answered. "The problem is, he's not weaned yet!"
