OK, new book about punctuation called Eats, Shoots & Leaves. The author according to Publishers Weekly: "A self-professed 'stickler,' Truss recommends that anyone putting an apostrophe in a possessive 'its'-as in 'the dog chewed it's bone'-should be struck by lightning and chopped to bits."
I skimmed bits of this book (and it is one to skim not read) and the first thought is that the only thing worse than a self-righteous crusader is one with no sense of humor. Second thought: There is something worse than a crusader with no sense of humor and that's one who thinks that she actually has one. Then again that's pretty much true of anybody.
