A guy was driving down the road in his Yugo during a thunder storm, when 
his windshield wiper broke. He drives until he comes to an auto body shop. 
He goes into the shop, walks up to the counter and says, "Excuse me,
but could you give me a windshield wiper for my Yugo?" The clerk leans 
against the counter and thinks for a while. Finally he says, "Sure...that 
sounds like a fair trade."
