A Lawyer and an Engineer were sitting next to each other on an airplane.
The Lawyer leans over to the Engineer and asks if he wants to play a fun game.
The Engineer just wants to sleep so he politely declines, turns away and
tries to sleep. The Lawyer persists and explains that it's a real easy game.
He explains,"I ask a question and if you don't know the answer you pay me $5.
Then you ask a question and if I don't know the answer I'll pay you $5."
Again the Engineer politely declines and tries to sleep.
The Lawyer, now somewhat agitated, says, "ok, if you don't know
the answer you pay me $5 and if I don't know the answer I pay you $50!"
Now, that got the Engineer's attention, so he agrees to the game.
The Lawyer asks the first question,
"What's the distance from the earth to the moon?"
The Engineer doesn't say a word and just hands the Lawyer $5.
Now, it's the Engineer's turn. He asks the Lawyer,
"What goes up a hill with three legs and comes down on four?"
The Lawyer looks at him with a puzzled look, takes out his laptop computer,
looks through all his references and after about an hour
wakes the Engineer and hands the Engineer $50.
The Engineer politely takes the $50 turns away and tries to return to sleep.
The Lawyer, a little miffed, asks, "Well what's the answer to the question?"
Without a word, the Engineer reaches into his wallet,
hands $5 to the Lawyer, turns away and returns to sleep.
