archangelbeth sagely observes:
Geeze, it's a BOOK. It's a BOOK in a BOOKBAG. Unless it's a hardcover, it's not even going to hurt very much if you bop someone with it. I mean, "Plow this ferry into the dock or I give you SUCH a papercut"? "If you don't let me steer, I'll show you -- BIG BOSOMED BIMBOS"?
