Einstein & a Gujju

Einstein & a Gujju 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..?

Gujju doesn't say a word,reaches his pocket,pulls out a $5..

Now,it's the Gujju's 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 Gujju $500..

Einstein going nuts and asks: Well,so what goes up a hill with three legs and comes down with four..?

Gujju reaches his pocket and gives Einstein $5.. 😄😄😄

Einstein fainted...😜😝😆😄😂
