I have a clock, which I brought overseas with me, that usually runs backwards. Every once in a while, it'll tick louder than other times. Every once in a while, it'll start running forwards.

It is just an alarm clock that runs on batteries. I'm unsure if the alarm function still works or if it keeps time, even though it runs the wrong way. It is weirdly one of my favorite possessions - in fact, "The Clock which keeps Untime" is generally the only visible clock in the house save for computer monitors.
