From a comment at Rod Dreher's blog: "Throughout human history....people have gone stark raven mad or crazy."
I like that. I had a post about that kind of thing not so very long ago--not craziness, I mean, but the phenomenon where someone substitutes for a word that was really part of a saying or idiom another that sounds like it, as in "tow the line." Though this one may just be an erroneous auto-correct that slipped by. Anyway, it's a rather striking image.
