A blonde and a lawyer are seated next to each other on a flight from Los Angeles to New York.

The lawyer asks if she would like to play a fun game. The blonde, tired, just wants to take a nap, so she politely declines and rolls over to the window to catch a few winks. The lawyer persists and explains that the game is easy and a lot of fun.

He says, "I ask you a question, and if you don't know the answer, you pay me five dollars, and vice versa."

Again, she declines and tries to get some sleep.

The lawyer, now agitated, says, "Okay, if you don't know the answer, you pay me $5, and if I don't know the answer, I will pay you $500."

This catches the blonde's attention and, figuring there will be no end to this torment, 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, reaches into her purse, pulls out a $5.00 bill, and hands it to the lawyer.

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

She asks, "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 ... no answer. He taps into the air phone with his modem and searches the Internet and the Library of Congress ... no answer. Frustrated, he sends e-mails to all his friends and coworkers but to no avail.

After an hour, he wakes the blonde and hands her $500.

The blonde thanks him and turns back to get some more sleep.

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

Without a word, the blonde reaches into her purse, hands the lawyer $5, and goes back to sleep.
