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 OK, 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 sun glasses. 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!"
