What the...?

[quasigeostrophy]

Just spent ten minutes tearing around the bookcase next to the computer desk in our home office trying to find the source of a noise. Out of nowhere, it started - blaring like a smoke detector, only not quite as loud. It wasn't any of the computer hardware. It wasn't the MP3 player. It wasn't the cordless phone. Turns out, it was a pedometer sitting on the bookcase. I have no idea why it was screeching like that. I don't recall that it's even supposed to make noise. I tried all the buttons, to no avail. I ended up having to loosen the battery cover and briefly remove the watch-style battery. Whatever...
