Cop pulls over a pick-up truck and while walking up notices a bunch of penguins in the back, "What are you doing with the penguins in the truck he asks?" "they are my penguins" responds the driver. "You can't have a bunch of penguins back there you need to take them to the zoo" "You're right sir I'll do that right away" and drives off.

Next week the cop pulls over the same pickup truck and sees the penguins still in the back but this time they are all wearing sunglasses. " I thought I told you last week to take those penguins to the zoo:"asks the cop. "You are exactly right officer and I did"..."This week I'm taking them to the beach"
