Indian and American ......must read !!

An Indian and an American are seated next to each other on a flight from Los Angeles to New York. The American asks if he would like to play a fun-game.
The Indian, tired, just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks.

The American persists and explains that the game is easy and a lot of fun.
He says, "I ask you a question, and if you don't know the answer, you pay me $5, and vice versa."
Again, the Indian declines and tries to get some sleep.

The American, now worked up, says, "Okay, if you don't know the answer, you pay me $5,and if I don't know the answer, I'll pay you $500."
This gets the Indian's attention and, figuring there will be no end to this torment, agrees to the game.

The American asks the first question, "What's the distance from the earth to the moon?"
The Indian doesn't say a word, reaches into his wallet, pulls out a $5 bill and hands it to the American.

"Okay," says the American, "Your turn."
So the Indian asks, "What goes up a hill with three legs and comes down with four legs?"

The American thinks about it. No answer.

Puzzled, he takes out his laptop computer and searches all his references. No answer!
He taps into the air-phone with his modem and searches the Internet and the Library of Congress. No answer.
Frustrated, he sends e-mails to all his friends and co-workers.
Checks the input. All to no avail!

Finally, a long time later, he wakes the Indian and hands him $500.
The Indian thanks him and turns back to get his sleep.

The American, more than a little miffed, stirs the
Indian and asks,"Well, what's the answer?"

Without a word, the Indian reaches into his purse, hands the American $5,
and goes back to sleep!
