This teacher is worse than Joffrey Baratheon.

A math teacher is replacing detention with something a little more dire — writing Game of Thrones spoilers on the board. On the French site DansTonChat, a student shared that his teacher, who already read George R.R. Martin's books, threatened to spoil deaths that haven't yet played out on the HBO show if the class failed to quiet down.

Unsurprisingly, the teacher saw immediate results. When the skeptical pupils tested his nerve, he promptly wrote out all the names of the characters who perished in Season 3. Any students who hadn't seen the Red Wedding yet were undoubtedly traumatized.

Suddenly staying after school — or worse, actually paying attention in class — doesn't seem so bad.
