Einstein & a Gujarati in a Plane

Einstein & a Gujarati 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…?

Gujarati doesn’t say a word,
Reaches his pocket,
Pulls out a $5…

Now…
It’s the gujaratis 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 gujarati $500…

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

Gujarati reaches his pocket and gives Einstein $5…

Einstein fainted…..
