A lawyer and a blonde are sitting next to each other on a flight from L.A. To New York. The lawyer asks if she would like to play a fun game. The blonde is tired and just wants to take a nap, so she politely declines and rolls over to the window to catch a few winks. The lawyer persists. He explains how the game works. "I ask you a Question, and if you don't know the answer, you pay me, and vice-versa." Again, the blonde politely declines and tries to get some sleep. The lawyer figures that since his opponent is a blonde he will easily win the match, so he makes another offer. "If you don't know the answer, you pay me only $5, but if I don't know the answer, I will pay you $500." The blonde figures there will be no end to this torment unless she plays, so she agrees. The lawyer asks, "What's the distance from the earth to the moon?" The blonde reaches in to her purse, pulls out a five-dollar bill, and hands it to the lawyer then she asks the lawyer "What goes up a hill with three legs, and comes down with four?" The lawyer is puzzled. He uses his laptop to search for references. He taps into the air-phone with his modem and searches the Net and the Library of Congress. Frustrated, he sends emails to his coworkers and friends. No luck. After an hour, he gives up. He wakes the blonde and hands her $500. The blonde politely takes the $500 and turns away to get back to sleep. The lawyer, who is going nuts trying to figure it out, wakes the blonde and asks, "Well, so what goes up a hill with three legs and comes down with four?" The blonde reaches into her purse, hands the lawyer $5, and goes back to sleep.
