The two clock radios in our bedroom both kaffed it recently. It is entirely possible that they both kaffed it at the same time. I did not notice. At first, I thought maybe the clock radios had simply been drained of power too long - when I deliberately had that circuit off for an extended duration - and that had caused them to .. I dunno... fail-to-thrive? (Do clock radios need companionship? Has anyone heard of a clock radio pulling all its feathers out?) I have been working on the electrical system in my bedroom over the month as part of a reno, and once, I shorted a line with a pair of wire strippers, popping a breaker. There were other things on that same breaker, including several lights, my TV and the cable box, none of which suffered any ill effects.
