Who walks into a restaurant eats shoots and leaves riddle

A panda walks into a restaurant, sits down and orders a sandwich. After he finishes eating the sandwich, the panda pulls out a gun and shoots the waiter, and then stands up to go. "Hey!" shouts the manager. "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 am a PANDA! Look it up!"
The manager opens his dictionary and sees the following definition for panda: "A tree-dwelling marsupial of Asian origin, characterised by distinct black and white colouring. Eats shoots and leaves."
