A lawyer and an older Iranian woman are sitting next to each other on a long flight. Pumped from winning an important case, the lawyer introduces himself and asks if she would like to play a fun game. The Iranian woman 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 woman'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 woman 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 Iranian woman'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 surfs the Net and even checks 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 Iranian lady and hands her $500. The woman 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 Iranian lady reaches into her purse, hands the lawyer $5 and goes back to sleep.
