A panda walks into a restaurant, sits down and orders a sandwich. He eats the sandwich, pulls out a gun, and shoots the waiter dead.

As the panda stands up to leave, the manager shouts, "Hey! Where are you going? You just shot my waiter and you didn't pay for your sandwich!"

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

The manager opens his dictionary and sees the following definition for panda: "A tree dwelling marsupial of Asian origin, characterized by distinct black and white coloring. Eats shoots and leaves."
