A panda walks into a bar and orders a sandwich. After finishing his meal, he whips out a gun and starts shooting up the place. The bartender, in a panic, asks why he's doing this.
The panda shrugs and says, "I'm a panda, it's what I do. Look it up."
Confused, the bartender pulls out his phone and looks up 'panda' in the dictionary. Sure enough, it reads: "Panda – a bear-like mammal native to China. Eats shoots and leaves."
