when i was younger, my family was watching a horror movie in the living room. there was a clock on the wall kinda by the tv. my sister happened to glance over at it and she said, "hey the clock stopped working." no sooner did she finish the sentence, the clock jumped off the wall and busted into pieces on the ground.
it was the same clock that stopped working 3 minutes after my grandpa died, 20 years earlier. it started working again on its own after a month or so, and hadn't ever had any issues until it killed itself during the movie.
