My high school chem teacher, while explaining soap micelles, went on a tangent saying that we don’t really need soap to wash ourselves and that he personally never used soap while bathing, I liked that teacher but TMI and gross.

My chemistry teacher didn’t understand why consumers complain about pesticides, since she claimed you could just rinse them off easily (which isn’t entirely accurate). She got cancer shortly after.

My anatomy and physiology teacher told the class he believed the entire Middle East should be nuked, after showing the wikipedia article on Ross Perot and talking about how the country is in decline because Perot lost the presidential election.

He also body shamed women during class, and told women that if they are behind on cooking dinner they can just throw some garlic and onion in a pan and their husbands would smell the good aromas and not know any better.

He also required students to dance and he video recorded every dance, this was not optional and had nothing to do with the curriculum, but it was treated very seriously like an end-of-class thesis. It doesn’t take much of an imagination to worry about what he was doing with those video tapes. This was at the same high school where it turns out one of the coaches was molesting the students.

I had a teacher who claimed that dinosaurs weren’t real. She said that people just naturally love patterns so when we find random bones we arrange them into shapes we like. Someone in the class said what about skulls that are just one bone and she ignored it lol.

That was many years ago and it’s still stuck in my memory as one of the dumbest things I’ve ever heard.

Only boring people get bored.

Utter nonsense but it was said to my boy by a junior school teacher. Was an interesting conversation when I talked to her at parent teacher day.

I had a teacher during sex ed start yelling about how you gotta work on and please your lady not a “wham bam thank you ma’am”, his words. Now not in 7th grade sex ed it wouldn’t have been so weird. Same teacher had a diabetic fit and started yelling and writing E over and over while grading our tests.

I had a teacher who believed that the moon landing was fake.

I remember in High School where we were pressured into having to choose a political party for our US Government class.

Yeah I thought the 2-party system was stupid then too and absolutely refused to pick a side. It was clear to me then, even as a teen, that people’s opinions change over time as they themselves change. Party loyalty is bullshit.

college instructor for Communication 101 went on several unprompted rants about how depression wasn’t real because it couldn’t be detected with brain scans

even though it, uh, absolutely can? also nobody asked you anyway dude???

History teacher told us that NASA found alien machines on the dark side of the moon.

Midway through his speech he fell asleep in his seated walker, woke up shortly after and then the been rang.

He was neither physically nor mentally fit to be a teacher.

A middle school teacher asked for an analogy about something, I don’t remember what specifically, but I raised my hand and excitedly said “Oh! Like how math can help you understand music and music can help you understand math?”

The teacher looked at me like I was a total fool and said “music has absolutely nothing to do with math, how could you possibly think that?”

Since I was a snarky little punk, and I knew I was right, I said “have you heard about the circle of fifths? Let me tell you about it” and I proceeded to explain the mathematical beauty of music to the entire class. I even had sheet music in my bag from my piano lessons, so I pulled it out and showed it to everyone to explain the bars, tempo, and time signature, all of which are based on mathematical principles.

She was not happy to be proven wrong in front of a class of fifth graders.

Not my story but from my boyfriend. In English class they were supposed to write a review about a movie. He wrote a negative one about The Last Airbender from M. Night Shyamalan. First she argued that “iceberg” is not an english word (this took place in Germany) and that he should instead use “icy mountain” they had to look it up in a dictionary to convince her otherwise and then she took points away because “why would you write a review about something and not recommend it”.

8th grade Earth Science teacher. I shared a fun little factoid I had just learned: if you’re standing on the North Pole, every direction is south.

She disagreed and spent like 20 minutes explaining why that was wrong. I didn’t understand most of what she was trying to convey, but I do remember hearing “you can go north but in a southerly direction.”

I forget if it was on the day or day after, but while the events of 9/11 were unfolding or coming to light I had a social studies teacher claim the plane that crashed in the field was an attack on our agriculture.

Not a teacher, per se, but the senior dev on my old team once said something that left me scratching my head. We were trying to troubleshoot an inconsistent bug in our software, and I said, “Maybe it’s a race condition,” to which he replied, “There’s no such thing.”

Still trying to figure out what he meant by that.

I had an intro to sociology prof spend an entire lecture on full blown anti vax conspiracy shit.

Also had a bio prof take 5 during an anatomy lecture to give a teary eyed plea for the young women in class to not ruin one of the ‘fundamental joys of motherhood’ by getting their nipples pierced.
