A lawyer and a blonde woman happen to be 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 like to play an fun game.The blonde is tired and just wants to take a nap,so she politely declines and roll over to the window to catch a few winks.
The lawyer persist,saying the the game is really easy and a lot of fun. He explains how the game work."Iask 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.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 pay you $500,"This catches the blonde's attention and.figuring the there will be no end to this torment unless she plays,she agrees to play the game.The lawyer ask the first question,"What's the distance from the Earth to the moon?" The blonde doesn't say a word,reaches in her purse,pulls out a five dollar bill,and hands it to the lawyer,Now,it's the blondes 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 references.He taps into the Air-phone with his modem and searches the net and even the Library of Congress.Frustrated he sends E-mail to all his coworkers and friends he knows....all to no avail.
After over and hour of searching for the answer he finally gives up.He wakes the blonde and handes her $500.The blonde politely takes the $500 and turns away to get back to sleep.The lawyer who cannot imagine what the answer is,and is going nuts trying to figure it out,is more than a little frustrated!He wakes the blonde and asks,"Well,so what goes up a hill with three legs and comes down with four?"
The blonde reaches in her purse and hands the lawyer a $5 spot says,"hell if i know",and goes back to sleep.

Moral: LET US SLEEP!!!
