“A panda walks into a cafe. He orders a sandwich, eats it, then draws a gun and fires two shots in the air.

"Why?" asks the confused waiter, as the panda makes towards the exit. The panda produces a badly punctuated wildlife annual and tosses it over his shoulder.

"I'm a panda," he says, at the door. "Look it up."

The waiter turns to the relevant entry and, sure enough, finds an explanation.

Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots and leaves.”
