A high school teacher in Belgium uses an amazingly creative method to keep his students quiet: Game of Thrones spoilers. A few months back he asked his students whom among them watched the series, to which most replied by raising their hands. He then proceeded to deliver the ultimate threat: “Well, I’ve read all the books. If there is too much noise, I will write the names of the dead on the board.” “They [the dead] are enough to fill the whole year and I can even describe how they die.”

Apparently, it only happened once.
