Going to the Zoo

There was this truck driver who had to deliver 500 penguins to the
state zoo. As he was driving his truck through the dessert he breaks
down. After about 3 hours he waves another truck down and offers the
driver $500 to take these penguins to the state zoo for him.

The next day the original truck driver arrives in town and sees the new
truck driver crossing the road with 500 penguins walking in single file
behind him.

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

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