48 Unforgettable Teacher Moments Students Still Talk About

Throughout our school years, we meet all kinds of teachers: strict ones, funny ones, boring ones. Most blur together with time, but a few stand out so much they stay in our memory long after graduation. 
Not because they were inspiring or life-changing, necessarily. Sometimes it’s because of the eye-raising stuff they pulled that still makes you wonder who approved their job application.
One Redditor recently asked people to share the most unhinged thing a teacher ever did in class, and the replies were exactly as chaotic as you’d expect. Scroll down to read the stories, and if you’ve got one of your own, feel free to drop it in the comments.

Unhinged in the best way. I once had a teacher give me $200 in cash once. He had overheard me crying to my friend about how my mother stole all the Christmas money i had saved up to buy my sisters gifts. We were very poor, and i wasn’t allowed to work, so once again my sisters weren’t getting ‘real’ gifts from me. I think i was a freshman in high school, maybe sophomore year.

Anyway, this teacher also knew my mother was struggling with addictions. He went home and told his wife, who also knew me, and they agreed to give me the money. He surprised me a week before Christmas break and I just remember sobbing.

Anyway, same teacher walked me down the aisle decades later. He was always one of the kindest men I had ever met and gave selflessly to his students. This man would have a fan club if we could lol.

One day a bunch of jocks jumped my friend, who was a small gay kid, and were beating him badly. The teachers couldn't even get into the mix to break it up.

Then suddenly our very tiny, female sociology teacher slipped in under the radar and started tearing jocks off my friend like a superhero and throwing them down the hall like rag dolls.

She taught me to never be afraid of bullies

Mr. Bloom earned the nickname Mr. Boom when he threw a desk so hard (toward, but not at, a certain student) that one of the legs punctured the wall and it just stayed there.

The student was a POS and said some real vile stuff (about Mr. Boom's recently deceased kid), so the whole class backed Mr. Boom and we all said the student did it.

Hyzenthlay87:

Really says a lot that an entire classroom of kids all agreed to lie about that!

OP:

Mr. Boom was a damn treasure and made learning fun. Which was super hard to do because he was a middle school history teacher in an underfunded district.

Unhinged in a fun way, but my Religion teacher put on the DreamWork’s movie “Prince of Egypt” for us in class one day. When it got to the part where the song “You’re Playing with the Big Boys Now” was about to play he paused the movie, told us it was his favourite song, and that he was going to sing along and that none of us could stop him. He proceeded to prance around the room like a Cabaret dancer, yelling the song at the top of his lungs, staring down whoever was the nearest student to him. Loved that guy.

Setso1397:

Love teachers who just enjoy their lessons like that. We had just finished a unit on Jack London, and it was end of year core testing, so the teacher let the class watch "call of the wild" movie. Towards the end, there was sniffling and the teacher was crying in the back of the room- "are you crying, miss B?"
She says "It's a dog movie! You're SUPPOSED to cry during dog movies!" She was fun.

My nine grade economics teacher opened a window and smoked a cigerette sitting on the sill. He told us he was giving us a lesson on addictions impact on people's abilities to do their jobs. .

My 6th grade science teacher brought bullfrogs and a blender into the classroom. She told our class she was going to make us a special bullfrog treat and took them into her “laboratory” [blender noises]

She comes out with the blender full of green mush and goes to each kids desk and scoops some out for us to eat… everyone was sobbing and screaming.

It was guacamole.

We had a teacher who needed to leave class to use the restroom one day and the teacher across the hall who could normally watch us both for a few minutes was on a field trip...

He took out his glass eye and put it on his desk and warned us "I'm watching you" while he left to do his business.

That's how some of us learned he had a glass eye.

rufferton:

My grandpa had a glass eye and he used to do this!

IJustWantToNapPlz:

I had a math teacher in 6th grade that would clean her glass eye during tests.

I feel like I’ve had a very sheltered school life 😂 the worse I can think of -

I went to a girls school. In biology, our beloved science teacher (Mr Christodoulou, very young and handsome, we all fancied him) was showing us a video on giving birth and he kept rewinding it right after that STRETCH when the head pops out, rewind, play, him maniacally laughing, rewind, play, while we all screamed and crossed our legs, rewind, play about 10 times!

Come to think of it, I don’t think we had any teen pregnancies that year so it worked! 🤣.

My Bio teacher in High School had another science teacher come in the classroom while he was teaching, have an argument with him and shoot him in front of all of the students. Everything was staged including fake blood, but it looked real enough to all of us.

Then he jumped up, and told us all to take our pulse. It was supposedly a way for us to experience the effect of stress or trauma.

Never found out what, if anything, happened to him or the other teacher.

itspurpleglitter:

Lmao. Surprise, kids! Here’s some ptsd!! 🤗

Vanishingf0x:

That’s insane. We did have two science teachers that would always interrupt the others lesson with some demo (both were chemists). So like one would walk in with a liquid on fire set it on the front table and leave just as the flame went out and the liquid changed color or would walk in with a piece of paper smack it as they left and it’d send sparks everywhere or they’d walk in with money on fire and throw it near the other who would stamp it out and show it wasn’t damaged at all, etc. Then after whatever happened the initial teacher would explain what was happening. It was always at a different time and often multiple times a week. I’m sure all those were planned things though and no one ever used a gun but there was often fire or a loud bang.

It was unhinged but in a good way. My chem teacher lit his desk on fire using alcohol and a taser to introduce us to one of our next chapters. Also built a cannon in the hallway. He went through around 100 ceiling tiles a semester.

afcagroo:

Mine decided to demonstrate thermite. He apparently made too much, and didn't think about the Styrofoam molecule models strung overhead. He also didn't use a thick enough crucible. While he was busy putting out the Styrofoam fires, the thermite melted through the countertop. We all got to go outside for a while so the firemen could do their job.

caughtyoulookinn:

For mole day he asked us to use our home ec skills to sew and stuff a plush mole and the best one got to get blown up in the classroom.

Way back, like late sixties we had a English teacher in high school who liked the sauce ...... Like a little too much. She would have kids water her flowers in the windows. There would have been nothing wrong with that if they weren't plastic.

mrnoire:

I was fond of my third grade teachers hugs because she smelled like my father's backyard parties. Years later I realized the smell was perfume and booze.

Made grill cheese on the radiator because “that’s how we did it in the ghetto growing up”.

ShadowBih42:

Math teacher regularly brought greens and other fragrant items for lunch, but she would put it on the radiator to slow warm for the entire morning. There was no escaping the… aromas. Nor will we ever forget her trimming her toenails at her desk, then using a clipping to pick her teeth.

Decided to show us how earthquake proof the lights were by hanging down from them. They were not indeed rated for such a test.

paraworldblue:

That's like the infamous story of the guy who wanted to demonstrate the strength of the glass in a skyscraper window by running and jumping into it. He was right that the glass wouldn't break, but the shit holding it in did break, sending him plummeting to his death along with the unbroken window pane.

My teacher locked me inside the classroom.

For context i fell asleep midclass and woke up when it was break time.

One of the best teachers ive had. He also liked to throw stuff at near me :D

-braquo-:

My brother had this brand new teacher. And my brother kind of made his first semester hell. So during second semester my brother fell asleep in class. The teacher quietly had everyone exit the classroom, and turned the clock ahead an hour. Then he acted like he'd just came into the class to find my brother asleep and made a lot of noise to wake him up. My brother panicked, grabbed all his stuff and ran out of the classroom. The rest of the class was in the hallway just laughing when he came running out of the class.

9th grade World History. Annoying entitled rich kid with Napoleon complex (he was a small guy) acted up, just nonstop verbal harassment. She picked his entire desk up, with him in it, and threw it out the door. Yes he was small and she looked fit, but that was a flex nobody saw coming and no one messed with her again.

I once had a drunk substitute in 8th grade who gave me a pass to the bathroom, then locked me out. I was a good kid and friends with the principal, so I just went to his office and told him what was going on. He walked back with me, asked me to try to knock again, and when the drunk sub yelled at me, he showed his face in the door window, and unlocked thr door woth his key. He smelled alcohol on her breath and found a pint of vodka in her purse (it was in plain sight). She was fired on the spot.

We had a French teacher who slept with one of the students in her classroom, I also had a teacher send me to the shop across the road and give me the money to buy him a newspaper and myself a pack of cigarettes so I could calm down and stop disrupting the lesson.

Pm_me_clown_pics3:

I had a teacher give me 2 bucks and told me to get him a coffee from the store across the street from our school. He said "if you're going to keep skipping my class at least be useful"

Poor dude had PTSD from Vietnam and ended up hiding under his desk and crying. It was awful. Thankfully, his best friend taught in the classroom next door and came over and helped him.

Not a teacher, but rather my bus driver in middle school. A Christian school. He was an amateur drag racer on the weekends. He would race beer trucks, big work trucks, other buses. We’d scream out the windows to goad the other truck drivers to race. They’d rev their engines and go from the red lights. It was so much fun.

My art teacher was the department head and the district made him order textbooks… he disagreed with being told how to spend his budget. First day of class, he borrowed a drill from the tech ed department with a huge bit and drilled the center out of one of the brand new books and said that’s what he thought of the school board telling him how to teach art, and encouraged us to use the textbooks for our first unit- paper mache! (Glossy textbook paper is not ideal for paper mache…).
