A lawyer and a blonde woman are sitting next to each other on a long flight from L.A. to New York. The lawyer leans over to her and 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, saying that the game is really easy and a lot of fun. He explains how the game works: "I ask you a question, and if you don't know the answer, you pay me, and visa-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. "Okay, how about this, 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." This catches the blonde's attention and, figuring that there will be no end to this torment unless she plays, she agrees to play the game. The lawyer asks the first question. "What's the distance from the earth to the moon?" The blonde doesn't say a word, reaches into her purse, pulls out a five-dollar bill, and hands it to the lawyer. Now, it's the blonde's turn. She asks the lawyer, "What goes up a hill with three legs, and comes down with four?" The lawyer looks at her with a puzzled look. He takes out his laptop computer and searches all his references. He taps into the Air-phone with his modem and searches the Net and even the Library of Congress. Frustrated, he sends E-mails to all his coworkers and friends he knows. All to no avail. After over an hour of searching for the answer he finally 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 more than a little frustrated, wakes the blonde and asks, "Well, so what goes up a hill with three legs and comes down with four?" Again without a word, the blonde reaches into her purse, hands the lawyer $5, and goes back to sleep.
