~~~ eachother on a plane and just after about 5-minutes into the flight the lawyer turns to the old guy asking if he'd like to play a game, but the old man seems to be disinterested. Then, the lawyer offers to explian how the game works. He tells the old man that he'll ask him a question and if he doesn't know the answer he's to give the lawyer $5... When the old man still seemed to be disinterested the lawyer explained that in the next round the old man is to ask a question, but if the lawer can't answer it he'll pay the old man $500. This seemed to excite the old man and he told the lawyer that he'd be happy to play the game and asked the lawyer what was the question. The lawyer then asks: "How far is it from earth to the moon?" and when the old man couldn't answer the question he gave the lawyer $5. The lawyer was all smiles and seemed very happy. Happy enough to buy a round of drinks. So, after they finish their drink the lawyer explains that it's now the old man's turn to ask a question... and the old man asks the lawyer: "What goes up a hill with three legs and comes down the hill with four legs?" The lawyer stops to think, scratches his head... pulls his phone out and starts to search the web for an answer but can't find anything so he hands over $500 to the old man... and he's not too happy at this point and justs sits back attempting to listen to some music, but after 15-minutes pass the lawyer turns to the old man and says... "Okay, tell me; what actually goes up a hill with three legs and comes down with four legs?"
