A man was sitting on a plane with Einstein one day and Einstein said to the man next to him I will give you 500 dollars every time I cant answer one of your questions. if you cant answer one of my questions you give me 5 dollars so Einstein asked a question the man did not know so he gave him 5 dollars so the man went next he said what walks up a hill with 2 legs but walks down with 3? Einstein went through all his information but he could not answer it. Einstein asked the man, What does walk up a hill with 2 legs and walk down with 3 legs? The man gave him 5 dollars. :)
