I'll happily disagree, Milo. I never heard anything on earth, other than in what I read above, about a colon suggesting an incongruity.
And for everybody here, here's what Holden Caulfield observes about commas and beyond:
That's something else that gives me a royal pain. I mean if you're good at writing compositions and somebody starts talking about commas. Stradlater was always doing that. He wanted you to think that the only reason he was lousy at writing compositions was because he stuck all the commas in the wrong place. He was a little bit like Ackley that way. I once sat next to Ackley at this basketball game. We had a terrific guy on the team, Howie Coyle, that could sink them from the middle of the floor, without even touching the backboard or anything. Ackley kept saying, the whole goddam game, that Coyle had a perfect build for basketball. God, how I hate that stuff.
