That was the warning made by one Belgian math teacher, who threatened to reveal major Game of Thrones plot spoilers if his noisy class didn't calm down, according to the Telegraph.
The teacher reportedly asked his unruly classroom which students watched the popular HBO fantasy drama, and when the majority raised their hands, he said, "Well, I've read all the books. If there is too much noise, I will write the names of [the characters who die] on the board."
But his crowd control plan wasn't just a one-day deal. "[The names] are enough to fill the whole year and I can even describe how they die," he said.
Apparently, the students decided they felt lucky, and pressed their teacher on his threat. But when he started to write the names of the characters killed on the board, the class quickly settled down.
The story spread on social media and had one admiring student writing, "My maths [SIC] teacher is a genius."
We concur. Even Tyrion would approve.
