A chaga and an American man are sitting next to each other on a long flight from London to New York.The American man leans over to the chaga and asks if he would like to play a fun game. The chaga just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks. The American man persists and explains that the game is real easy and is a lot of fun. He explains "I ask you a question, and if you don't know the answer, you pay me $5. Then you ask me a question, and if I don't know the answer, I'll pay you $5."Again, the chaga politely declines and tries to get to sleep. The American man, now somewhat agitated, says, "OK, if you don't know the answer you pay me $5, and if I don't know the answer,I'll pay you $100!" This catches the chaga's attention, and he sees no end to this torment unless he plays, so he agrees to the game. The American asks the first question. "What's the distance from the earth to the moon?" The chaga doesn't say a word, but reaches into his wallet, pulls out a five dollar bill and hands it to the American. Now, it's the chaga's turn. He asks the American "What goes up a hill with three legs, and comes down on four?" The American looks up at him with a puzzled look. He takes out his laptop computer and searches all of his references. He taps into the Airphone with his modem and searches the net and the Library of Congress. Frustrated, he sends e-mail to his co-workers-all to no avail. After about an hour, he wakes the chaga and hands him $100. The chaga politely takes the $100 and turns away to try to get back to sleep. The American, more than a little miffed, shakes the chaga and asks "Well, so what's the answer?" Without a word, the chaga reaches into his wallet, hands the American $5,and turns away to get back to sleep.
