[quote]Throw most SFs a tin of Tuna and ask them to get to the contents without a P-38 and they would be stuffed
Reminds me of an old joke about a physicist, a mathematician, and an economist who get lost in the desert with only a can of beans and no can opener. They set to arguing about how to open the tin.
The mathematician suggests putting the tin on a hard surface and dropping a big rock on it to burst it open.
The physicist ridicules this notion and suggests building a campfire and placing the tin in the middle, so it will burst open from the heat. The mathematician finds this notion equally silly.
As they are arguing, the economist starts laughing at them. "Why do you need to make it so complicated?"
"Okay," they ask him, "how would you do it?"
"Easy," says the economist. "First of all, let's assume we have a can opener..."
For the vast majority of you who just went 'HUH?', the joke is that mathematicians are always accusing economists of basing their theories on unproven or even unrealistic assumptions about the real world. I tell the joke just to make the point that such "friendly rivalry" isn't confined to the armed forces of the world. :-)
