I thought I had some strange teachers in my time, but none as strange as this Manchester teacher who told her students that a meteor was going to hit the earth in a week and they were all going to die. Her point: to motivate them to 'seize the day'. The logic seems to be 'make them think they're going to die so they appreciate what they have.' Kind of like that guy who tried to save his marriage by electrifying his wife in the bathtub.

On a completely unrelated note, the widespread use of the phrase seize the day (from the latin carpe diem) is a pet peeve of mine, since I think it's mistranslated. The latin word carpe is principally an agricultural term meaning to harvest, pluck, or gather. It only secondarily has a military usage. So the phrase should really be translated as harvest the day, which is a lot more laid back than seize the day. Though maybe my real problem with the term are those people who are always lecturing other people to seize the day.
