This one is GOOD!

A lawyer and a blonde woman are sitting next to each other on a long flight. 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 tries to catch a few winks.
The lawyer persists, that the game is a lot of fun. 'I ask you a question, and if you don't know the answer, you pay me only $5; You ask me one, and if I don't know the answer, I will pay you $500.'
This catches the blonde's attention; and, to keep him quiet, 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 in to 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 uses his laptop, searches all references. He uses the Airphone; he searches the Net and even the Library of Congress.
He sends e-mails to all the smart friends he knows, all to no avail. After one hour of searching he finally gives up.

He wakes up the blonde and hands her $500. The blonde takes the $500 and goes back to sleep.
The lawyer is going nuts not knowing the answer.
He wakes her up 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!!
