Joke:Differences between an engineer and a programmer

A computer programmer and an engineer were sitting next to each other on an airplane. the programmer leans over to the engineer and ask 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 programmer persists and explains that it's real easy game. He explains, "I ask 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'II pay you $5." again the engineer politely declines and tries to sleep.

The programmer, now somewhat agitated, say, "O.K., 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 ettention, so he agrees to the game. The programmer asks the first question, "What's the distance from the earth to the moon?" Then the engineeer doesn't say a word and just hand the programmer $5.

Now, its the engineer's turn. He asks the programmer, "What goes up a hill with three legs and comes down on four?" The programmer looks at him with a puzzled look, takes out his notebook computer, looks through all his references and after about half 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 programmer, a little miffed, ask, "well what's the answer to the question?" without a word, the engineer reaches into his wallet, hands $5 to the programmer, turns away and return to sleep.
