Teachers threaten misbehaving students with 'Avengers: Endgame' spoilers

"When the weather is warm and the years almost over, the usual method of reminding them that their grade will be affected, or warning that you will call home, doesn't make an impact," she said. "But the one thing I know my students care about is Endgame.
