A blonde and a man are on an aeroplane. The man asks the blonde if she wanted to play a game. She said yes. The game was if the blonde can't answer one of the man's questions, she gives him $5, if the man can't answer 1 of the blonde's questions, he gives her $30.
The man askes the blonde a bunch of questions and she doesn't answer any of them right. He gets really rich. Then the blonde askes him "What goes up a hill on 3 legs and comes down on 2?" The man walks up and down the aisle's asking each person, and gets nothing and gives the Blonde 30$. Then he asks "I give up. What's the answer?"
The blonde gives him $5.
