My brother will quote jokes five seconds before they happen when we're watching old episodes of The Simpsons, Futurama or Scrubs. It's really annoying. I mean, I've watched these episodes before too, but unlike him I don't have them memorized and hearing jokes before they happen ruins any chance I have of being surprised and getting any enjoyment out of them on a second/third/fourth viewing.
I've never had any bad cinema experiences, though (that weren't caused by bad movies, anyway), but that might be because I only go to the movies about once a year and generally towards the end of a movie's run.
