The explanation of the fish: I think it was somewhere in the Mudcat but honestly I don't remember. Anyway the conversation turned to the Icthus, the little Christian fishy symbol that a lot of folks like to put on their cars, and all its variations. There's a Darwinian fish with legs on it, and apparently another one of a fish eating a fish. (I haven't seen that one.) But the writer wanted to know why we couldn't each just have our own dang fish, instead of having to conquer everyone else's fish. (Does anyone else remember that besides me?)
