A Geologist and a developer are sitting next to each other on a long flight from LA to NY. The Geologist leans over to the developer and asks if he would like to play a fun game. The Developer just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks. The Geologist persists and explains that the game is real easy and a lotta fun. He explains, "I ask you a question, and if you don't know the answer, you pay me $5. Then you ask me a question, and if I don't know the answer, I'll pay you $5." Again, the Developer politely declines and tries to get to sleep. The Geologist 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'll pay you $50!"

This catches the Developer's attention, and he sees no end to this torment unless he plays, so he agrees to the game. The Geologist asks the first question. "What's the distance from the Earth to the moon?"

The Developer doesn't say a word, but reaches into his wallet, pulls out a five dollar bill and hands it to the Geologist.

Now, it's the developer's turn. He asks the Geologist, "What goes up a hill with three legs, and comes down on four?" The Geologist looks up at him with a puzzled look. He takes out his laptop computer and searches all of his references. He taps into the Airphone with his modem and searches the net and the Library of Congress. Frustrated, he sends e-mail to his co-workers -- all to no avail.

After about an hour, he wakes the Engineer and hands him $50. The developer politely takes the $50 and turns away to try to get back to sleep.

The Geologist is more than a little miffed, shakes the developer and asks, "Well, so what's the answer?"

Without a word, the developer reaches into his wallet, hands the Geologist $5, and turns away to get back to sleep.
