my favorite line from the book i'm reading now: "In other words, a bunch of guys who spent their time running around the woods, hunting and fishing and trading meat for sex, one day saw someone hoeing weeds and said to themselves, 'What a fine idea! Let's go do that instead.'" this probably doesn't ring quite so truly if you've never hoed weeds, but believe me, it makes agriculture seem like a pretty dumb idea, indeed.
