penguin

A guy found a penguin and showed him to a policeman.
The policeman said, "Take that penguin to the zoo, now."

Next day the policeman sees the man with the penguin again.

The policeman stops the guy and says, I told you yesterday to take the penguin to the Zoo, what on earth are you doing with the penguin in your truck again?"

The guy says, "What is there to do? Yesterday I took him to the zoo and today I'm taking him to the movies."
