A blonde and a lawyer

A blonde and a lawyer are seated next to each other on a flight from LA to NY. The lawyer asks if she would like to play a fun game?
 
"Okay, if you don't  know the answer you pay me $5.00, and if I don't know the answer, I will pay  you $500.00."

This catches the blonde's attention and agrees to the game.

The lawyer asks the first question. "What's the distance from the earth to the moon?"

The blonde doesn't say a word pulls out a $5.00 bill and hands it to the lawyer.

"Okay," says the lawyer, "your turn."

She asks the lawyer, "What goes up a hill with three legs and comes down with four legs?"

The lawyer, puzzled, takes out his laptop computer and searches all his references. He taps into the air phone with his modem and searches the net and the  library of Congress, no answer. Frustrated, he sends e-mail to all his friends  and coworkers, to no avail. After an hour, he wakes the blonde, and hands her  $500.00.

The blonde says, "Thank you," and turns back to get some more sleep.

The lawyer, who is more than a little miffed, wakes the blonde and asks, "Well, what's the answer?"

Without a word, the blonde reaches into her purse, hands the lawyer $5.00, and goes back to sleep.
