Nothing makes high school more of a miserable experience than a terrible teacher. We all had that one class that we dreaded walking into because we knew they’d be there. This former student was berated and bullied by his algebra teacher throughout his senior year, but decided to put an end to it, and is now sharing his incredible story of revenge almost 16 years later.

The Reddit user (Johnny_Provolone) who posted the cautionary tale was only 18 when it all happened, and went on to graduate with the class of 2001. He is now 34 and is studying diesel mechanics. His post has gone viral on Reddit’s ProRevenge thread, garnering a whopping 26.8 thousand upvotes.
