John was piloting a plane behind a car but was never able to overtake it. Why?

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."

How did the man win the bet?
