A boy was at a carnival and went to a booth where a man said to the boy
If I write your exact weight on this piece of paper then you have to
give me $50 but if I cannot I will pay you $50.The boy looked
around and saw no scale so he agrees thinking no matter what the carny
writes hell just say he weighs more or less.In the end the boy ended up
paying the man $50. How did the man win the bet?
