A police officer sees a man driving around with a pickup truck full of
penguins. He pulls the guy over and says, "You can't drive around with
penguins in this town! Take them to the zoo immediately."
The guy says okay, and drives away. The next day, the officer sees the guy
still driving around with the truck full of penguins -- and they're all
wearing sunglasses. He pulls the guy over and demands, "I thought I told you
to take these penguins to the zoo yesterday?"
The guy replies, "I did. Today I'm taking them to the beach!"
