A panda walks into a bar, sits down, and orders a sandwich.
The waiter returns with the sandwich in short order.
The panda eats the sandwich, pulls out a gun, and shoots the waiter dead.

As the panda stands up to go, the bartender shouts,
"Hey, you! Where are you going? You just shot my waiter
and you didn't even pay for your sandwich!"

The panda yells back at the bartender, "Hey, man, I'm a PANDA! Look it up!"
and stomps out of the bar.

So the bartender opens his trusty Webster's and looks up 'panda'.
There he finds the following definition:

"Panda: A tree-dwelling marsupial of Asian origin,
characterized by distinct black and white coloring.
Eats shoots and leaves."
