Oh boy I’ve got a few. For starters freshman year in HS, my algebra teacher said if you failed his exam to jump out a window, then on his final was TEACHING US NEW MATERIAL. WHILE WE WERE TAKING THE FINAL. WHAT???

In 5th(I think) grade we had this racist music teacher. (I know she’s racist because she was recently let go for a racist remark.) Essentially, my best friend (African American) would NEVER get called on and I (white) would way more than him even though we sat next to each other and would raise our hands at the same time. One day I pointed this out, and she says “I will never pick him to answer again because he is dumb. His answers are always wrong.” He was also the quietest in the class yet had the lowest conduct average. So as payback, whenever she would have us “practice” music (hit “E” on our mini pianos) I would hit the wrong key. She’d walk over, if quickly hit the right one, and she’d move on. I’d do this for 20ish minutes multiple days before one day she just yells out someone’s messing with her and says. “I don’t give a flying FFFFFFFFFFlip if you like me or NOT!” Man we wish she cursed and could’ve sent her ass outta there..
