A panda walks into a cafe. He orders a sandwich, eats it, then draws a gun and proceeds to fire it at the other patrons. ""Why?"" asks the confused, surviving waiter amidst the carnage, as the panda makes towards the exit. The panda produces a badly punctuated wildlife manual and tosses it over his shoulder. ""Well, I'm a panda,"" he says. ""Look it up."" The waiter turns to the relevant entry in the manual and, sure enough, finds an explanation. ""Panda. Large black-and-white bear-like mammal, native to China. Eats shoots and leaves.""
