I'm not sure this really fits in, but it's kind of cute.

A koala goes into a restaurant and orders dinner. The waiter brings the food, the koala eats it, pulls out a gun and fires at the waiter then exits the restaurant.

Later, after being arrested, the police ask the koala why he did it. The koala simply handed the police a dictionary.

Under the word 'koala' it read 'eats shoots and leaves'.
