Trucker gets pulled over while hauling a load of sheep. Cop says "You don't have a permit to haul these sheep. Take them to the zoo." Next day, cop pulls over same truck. Still full of sheep. But now they are all wearing sunglasses. Cop says "I told you to take these sheep to the zoo." Trucker says "I did. We had such a good time, today I am taking them to the beach."
