Freshman year in my high school, physical education began the semester with swimming. We did it nude. Over one hundred naked boys in the pool at the same time. Nobody ever explained why we couldn't bring swimsuits.

Went to a rural high school that let the FFA and 4H kids out for days to show their animals, but said no to the National Honor Society kids for wanting a day to go to an art festival because the administration was afraid we couldn't make up our work, sigh.

I was riding the bus to school one day. My bus developed problems and had to pull onto the shoulder of a highway . Another bus stopped on the highway beside us to inquire what the problem was. I heard tires screeching and turned just in time to see my drivers ed teacher rear-end the other bus. He banged his head on the windshield of his VW Beetle, but was not seriously injured. There were no seat belts in the early 70's.

Oh, they also had karaoke hour during lunch...

We had a class all of the students called AP Coloring. It was Geography. The teacher assigned map coloring, and he was very particular. I once used markers instead of colored pencils, and I had to stay after class so he could explain why that was a problem.

My society/world culture teacher spent over ten years in s. Korea, had pictures of himself all over the world when he was a younger man, and was fluent in multiple languages. He often hosted snack days once a month when we started a new section/region with coman food from that current place we were learning about. He was just the most chill dude you could imagine . . . Probably because he smoked weed with the chemistry teacher and spiked his morning tea with vodka he kept locked in his safe under the desk 🤣 he also had a habit of telling you to sit down and shut the hell up if it got too loud in class. My favorite though, was the fact that he was the go to translator for many FES in out school, and he straight up talked crap about the other teachers with them whenever he was asked to help them out. My school has also had various farm animals (chickens, a cow, donkeys, pigs, and I think a wild litter of racoons, but dunno if it was related) in the gym for senior prank.

My principal got on my ass for being late for a class in our tech center. (This was a building at the old high-school a couple blocks away use for all the "techy" stuff "autoshop, woodshop, computer stuff, home ech...") anyway, he got all mad cause I was walking through the door as the bell rang, he accused me of being a druggie and blah blah, I pretty much told him off, and that I'm actually a really good student, so he responded with, I will make sure you are marked tardy in this class... I was like ok.. whatever. The next day he pulled my to the side in the school to apologize, saying he'd looked at my school transcripts and records, and to tell me he'd fixed that tardy since it was his fault I'd actually been tardy, then he kissed my ass the rest of that school year, wanting to buy jewelry I'd made in class and all kinds of weird stuff.

Not high school but elementary school, my principal once crossed dressed as a peocock and let us kids silly string him

I was voted "most likely to lead a cult"
