A lawyer and an elderly Jewish man are sitting next to each other on a long flight.
The lawyer is thinking that Jews are so dumb that he could get over on them easy...so the lawyer asks if the Jew would he like to play a fun game.
The old Jewish man 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 Jew'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 elderly Jew 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 Jew'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 Jewish man and hands him $500.
The old Jew pockets the $500 and goes right back to sleep.
The lawyer is going nuts not knowing the answer.
He wakes the elderly Jew up and asks, 'Well, so what goes up a hill with three legs and comes down with four?'
The Jew shrugs, reaches in his pocket, hands the lawyer $5 and goes back to sleep.
