The Question That Stumped Einstein

One day while working in his lab, Einstein was teaching his student The student was in awe of the brilliance of the genius The youngster had an idea he thought to be prudent Trying to outwit Einstein, one might say...to be ingenuous The youngster made a bet, declaring to pay five dollars if he couldn't figure out the answer to Einstein's question But if Einstein couldn't answer his question, he would pay him five hundred dollars "Bet on" replied Einstein So, Einstein asks the youngster a question he couldn't possibly answer The youngster reaches in his pocket and gives him five dollars That was a question that only a great mind as yours would be able to answer But let me ask you... what has three legs, runs up a mountain...and comes down with five legs? Einstein is puzzled and could not answer the question- so he reaches in his pocket and gives the youngster five hundred dollars After giving him the money Einstein asks the youngster- "so what is the answer to the question" Smiling happily, the youngster reaches in his pocket and gives Einstein another five dollars
