A lawyer and a senior citizen are sitting next to each other on
> a long flight.
>
> The lawyer is thinking that seniors are so dumb that he could
> get one over on them easy.
>
> So the lawyer asks if the senior would like to play a fun game.
>
> The senior is tired and just wants to take a nap, so he politely
> declines and tries to catch a few winks.
>
> The lawyer persists, saying that the game is a lot of fun.
> I ask you a question, and if you don't know the answer, you pay
> me only $5. Then you ask me one, and if I don't know the
> answer, I will pay you $500, he says.
>
> This catches the senior's attention and, to keep the lawyer
> quiet, he agrees to play the game.
>
> The lawyer asks the first question. 'What's the distance
> from the Earth to the Moon?'
>
> The senior doesn't say a word, but reaches into his pocket,
> pulls out a five-dollar bill, and hands it to the lawyer.
>
> Now it's the senior's turn. He asks the lawyer, 'What goes
> up a hill with three legs, and comes down with four?'
>
> The lawyer uses his laptop and searches all references he can
> find on the Net.
>
> He sends e-mails to all the smart friends he knows; all to no
> avail. After an hour of searching, he finally gives up.
>
> He wakes the senior and hands him $500. The senior pockets
> the $500 and goes right back to sleep.
>
> The lawyer is going nuts not knowing the answer. He wakes
> the senior up and asks, 'Well, so what goes up a hill with three
> legs and comes down with four?'
>
> The senior reaches into his pocket, hands the lawyer $5, and
> goes back to sleep.
