A truck driver is driving a truckload of penguins to zoo in the next town, when his truck breaks down. While he’s working on the truck , another truck driver says, “If I gave you $100, would you take these penguins to the zoo ?” The second trucker agrees to do it. Hours later, the truck driver is still trying to fix his truck when the second truck driver drives past with all the penguins still in his truck. The puzzled first truck driver says, “Didn’t you take them to the zoo?” The second truck driver say, “Yes, we went to the zoo, and there was money left over . So now we’re going to the movies.”
