Anyone heard this one?

A panda walks into a bar, sits down and orders a sandwich.
He eats, pulls out a gun and shoots the waiter dead.
As the panda stands up to go, the bartender shouts: Hey! Where are you going? You just shot my waiter and you didn't pay for the food! The panda yells back: Hey man, I'm a panda. Look it up!
The bartender opens his dictionary to panda: (A tree-climbing mammal of Asian origin, characterized by distinct black and white coloring. Eats shoots and leaves.)

"Life does not cease to be funny when people die any more than it ceases to be serious when people laugh"
