Avengers: Endgame may have just surpassed Titanic at the box office to become the second biggest film ever, but those who have yet to see it are increasingly vulnerable to spoilers.
- Avengers fans brutally beat man outside cinema for revealing Endgame ending
- Endgame viewer hospitalised for 'uncontrollable sobbing'
Some high school teachers have decided to capitalise on that by threatening to reveal crucial plot points from the film if their students step out of line.
Reddit user Heroic0 shared that their teacher had been filling a new blank in a spoiler sentence written on the whiteboard every time the class became unruly.
According to Insider, several other teachers have followed suit, finding the method to be a highly effective one.
"I told him that if he didn't stop distracting people right now, I would tell him an Endgame spoiler," one New York City teacher said of a student.
"I could see his eyes widen, and immediately he closed his mouth and turned towards the assignment. I have literally never seen such an instantaneous result with a student."
The inventive new punishment has prompted outrage from students who have shared their frustration online.
"IS MY TEACHER F**KING SERIOUS," one high school pupil captioned a video of a whiteboard with a spoiler threat written on it.
While the approach appears to be working, it's not in line with the filmmaker's philosophy when it comes to spoilers.
"Because so many of you have invested your time, your hearts, and your souls into these stories, we're once again asking for your help," the Russo brothers wrote in a statement.
"When you see Endgame in the coming weeks, please don't spoil it for others, the same way you wouldn't want it spoiled for you."
