Penguin Breakdown

A truck driver had to deliver five hundred penguins to the state zoo.
As he was driving his truck through the desert, the truck broke down.
After waiting by the side of the road for about three hours, he waved
another truck down and offered the driver $500 to take the penguins to
the state zoo for him.

The next day, the first truck driver arrived in town and saw the
second truck driver crossing the road with 500 penguins walking in
single file behind him.

The first truck driver jumped out of his truck and said, "What's going
on? I gave you $500 to take these penguins to the zoo!"

The second truck driver replied, "I did take them to the zoo. And I
had money left over, so now we're going to see a movie."
