Einstein & a Indian sitting next to each other on a long flight...
Einstein says: "Let's play a game... I will ask you a question, if you don't know the answer, you pay me only $5 and if I don't know the answer, I will pay you $500..."
Einstein asks the first question: What's the distance from the Earth to the Moon...?
Indian doesn't say a word, Reaches his pocket, Pulls out a $5...
Now... It's the indian turn...
He asks Einstein: What goes up a hill with 3 legs and comes down on 4 legs..?
Einstein searches the net and asks all his smart friends... After an hour he gives Indian $500...
Einstein going nuts and asks: Well... so what goes up a hill with three legs and comes down with four..?
Indian reaches his pocket and gives Einstein $5...
