This man walks into the police station holding a penguin. He says to the officer behind the counter, “Sir, I found this penguin.” 

The officer says “Why did you bring it here? Bring it to the zoo!”

The man thanks the officer and heads out the door.

A week later, the same officer is driving down the street and he sees the same man as before at a bus stop and he’s still holding the penguin! The officer stops the car and yells out the window “Hey buddy! I told you to bring that penguin to the zoo!”

The man yells back “Oh, I did! We had so much fun we’re going back today!”
