This joke is here just because I love penguins!

A man was driving down the road with twenty penguins in the back seat. The police stop him and say that he can't drive around with the penguins in the car and should take them to the zoo. The man agrees and drives off.
The next day the same man is driving down the road with twenty penguins in the back and again. He is stopped by the same police officer who says, "Hey! I though I told you to take those to the zoo."
The man replies "I did. Today I'm taking them to the movies." 

(I know the picture doesn't quite relate to the joke but I still thought the picture was funny!)
