The game

 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-mail's 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.
