This is an old joke that my teacher told me when I was little and most people probably already know it but I remember loving it.

A police officer pulls over a man who has penguins in the backseat of the car.
“Sir you can’t have penguins in your car. Bring them to the zoo or something,” the police officer tells the man.
The next day, the police officer sees the man again. Again, the penguins are in the backseat of the car.
“Sir, I told you to take the penguins to the zoo!”
“I did, Officer! Today I’m taking them to the movies.”
