According to a post on French website DansTonChat, a math teacher threatened his students with Games of Thrones spoilers if they did not start behaving.
The teacher thought of the punishment after he asked how many of his 70 students watched the popular HBO show and nearly 75 percent raised their hands.
“Well, I’ve read all the books,” he told the class, according to a rough translation. “If there is too much noise, I will write the names of the dead on the board. They are enough to fill the whole year, and I can even describe how they die.”
There was some giggling, so the unnamed teacher proceeded to list the names of the characters who died in season three of the show.
The fourth season of the show will debut on April 6.
The student who posted about the situation wrote that there was a “religious silence” after the teacher wrote the names on the board and referred to the teacher as a “genius.”
