OK I did not make this, I found it on the internet a couple of years ago, but its funny.
A lawyer and a blonde are sitting next to each other on a long flight from New York to Beijing. The lawyer, seeing that his seat mate was a blonde, leans over and asks if she wants to play a fun game. The blonde is really tired and would rather like to sleep, and she says so.
The lawyer persists and says the game is fun and easy. He says "I ask you a question and if you don't know the answer you pay me $5. Then it is your turn to ask me a question."
Again the blonde declines.
The lawyer, somewhat agitated at this point, says "Okay, if you don't know the answer you pay $5, and if I don't know the answer, I pay you $50" he says, figuring that he will win so much and that she won't win once.
This catches the blondes attention and she figures that he won't stop tormenting her until she plays.
The lawyer asks the first question, "What is the distance between Earth and the moon. The blonde says nothing, reaching ino her purse and pulling out a five dollar bill. Now it is the blonde's turn. She asks, "What goes up a hill with three legs and comes down with four?"
The lawyer looks at her with a puzzled look, takes out his laptop and searches all his references. He taps into the air phone with his modem and searches the internet and the library of congress. Frustrated he sends e-mails to all his coworkers and friends, all to no avail.
After over an hour he wakes the blonde up and hands her a $50 dollar bill.
The lawyer, somewhat annoyed that he just lost FIFTY DOLLARS, asks, "Well, what IS the answer?!!" Without a word the blonde reaches into her purse, hands the lawyer $5, and goes back to sleep.
