I was sitting in the, er, library reading with the door closed and heard a crash in the bedroom. I swung the door open and the floor register wasn't in the hole. The register was found on the bed and there is a ding in the headboard. Wife was in the kitchen, she came in ans asked me what happened. We have a large dog, I assumed his collar might have gotten caught or something but he was asleep on the couch and when I called him in to the register he just sniffed it, didn't appear afraid of it or anything. HMMMM,
