Koala Encounter

A Koala walks into a restaurant, sits down and orders dinner.
After he has finished eating, the waiter brings him his bill.
The koala shoots the waiter and heads for the door.
The restaurant owner runs over and stops him.
"You can't come into my restaurant, eat my food, kill my waiter and then walk out! Who do you think you are?"
The koala says "A Koala. Look it up."
The owner gets a dictionary and looks up koala.
It says, "Marsupial. Eats shoots and leaves".
