Panda

A panda walks into a diner, sits down, and orders a sandwich. He eats the sandwich, pulls out a gun, and shoots out the restaurant's windows.

As the panda stands up to go, the owner shouts, "Hey! Where do you think you're going? You just shot my windows out and you didn't pay for your sandwich!"

The panda yells back at the owner,"Hey man, I'm a PANDA! Look it up!"

The owner gets out a dictionary, looks it up, and sees the following definition for "panda". . . . . . A tree dwelling marsupial of Asian origin. Eats shoots and leaves."
