A panda walks into a bar and orders a sandwich and a beer. After seemingly enjoying his meal, he pulls out a revolver and plugs the piano player.
"What are you doing?" asks the bartender.
"I'm a panda, and I'm doing what I'm supposed to do. Look it up!" replies the panda as he walks out the door.
Wondering what that was all about, the bartender opens a dictionary, the only reference book he has, and there it is:
"Panda: A large bear-like animal. Eats shoots and leaves."
