During a long haul flight

One day during a long flight A lawyer and a Chinese are sitting next to each other on a long flight.  The lawyer is thinking that all Chinese are dumb that he could get  over on them, easy. 

So the lawyer asks if the Chinese would like to play a fun game. The Chinese is tired and just  wants to take a nap, so he politely declines,  and tries to catch a few winks. The lawyer persists, and says 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, he says..

This catches the Chinese's attention and to keep the lawyer quiet, he  agrees to play the game.  the lawyer asks the first question. 'What's  the distance from The Earth to the Moon?' The Chinese doesn't say a word, reaches in his pocket, pulls out a five-dollar bill, and hands it
to the lawyer. 

Now, it's the Chinese's turn. He asks the lawyer, 'What goes up a hill  with three legs, and comes down with four?' The lawyer uses his laptop and searches all references he could find on the Net. 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 Chinese and hands him $500. The Chinese  pockets the $500 and goes right back to sleep. The  lawyer is going nuts not knowing the answer. He wakes the Chinese up and asks, 'Well, so what goes up a hill with three legs and comes down  with four?" 

The Chinese reaches in his pocket, hands the lawyer $5 and goes back  to sleep. 

Happy reading!  and have a great laugh
