A businessman gets on a plane and realizes he is sitting next to a pretty lady. He wants to get to know her so he says to her, "Hey, lets play a game. We go back and forth asking each other questions, and if we don't know the answer, we give the other $5." The lady isn't interested and she shakes her head. A few minutes later, the businessman asks the lady, "How about we play the same game but if you don't know an answer you give me $5 and if I don't know the answer I give you $300." The lady, interested in the money, agrees. She thinks for a moment about her question, and says, "What goes up with one leg and comes down with two?" The businessman is stumped. For the rest of the flight, he thinks and thinks, but can't think of the answer. When the plane lands and everyone leaves, the businessman catches up to the lady and says, "I don't know the answer, here is your money." as he pulls $300 out of his wallet. "Oh and by the way, what was the answer to the question?" The business man asks. "It's killing me!" The lady calmly took $5 out of her bag and handed it to him.
