He explains how the game works: "I ask you a question, and if you don't know the answer, you pay me, and visa-versa."
Again, she politely declines and tries to get some sleep. The chauvinistic lawyer figures that since his opponent is a blonde he will easily win the match, so he makes another offer:
Okay, how about this "If you don't know the answer you pay me only NULL, but if I don't know the answer, I will pay you NULL0."
This catches the blonde's attention and, figuring that there will be no end to
this torment unless she plays, she agrees to play 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 in to her purse, pulls out a five-dollar bill, and hands it to the lawyer.
Now, it's the blonde's turn. She asks the lawyer, "What goes up a hill with three legs, and comes down with four?"
The lawyer looks at her with a puzzled look. He takes out his laptop computer
and searches all his references. He taps into the Airphone with his modem and
searches the Net and even the Library of Congress. Frustrated, he sends E-mails to all his co-workers and friends he knows. All to no avail.
After over an hour, of searching for the answer he finally gives up. He wakes the blonde and hands her NULL0.
The blonde politely takes the NULL0 and turns away to get back to sleep.
The lawyer, who is more than a little frustrated, wakes the blonde and asks, Well, so what IS the answer?"
Again without a word, the blonde reaches into her purse, hands the lawyer NULL,
and goes back to sleep.
