My choir teacher last year was teaching us the song Blackbird and was giving the Baritones their starting note.
He didn't state it well, and said, "Okay, I'm going to give you the D"
Everyone started dying and he just looked petrified for a minute because he didn't get it yet.
He closed the door and sat down and told us,
"What happens in the next five minutes of this class are between you guys and me."
Some girl started to explain and just before she said what "The D" stood for, he yelled "OKAY OKAY I GET IT OH MY DEAR LORD."
I miss him.

I also had a substitute bus driver (not a teacher so to say) who looked like Jesus and had a YouTube channel.
He was cool.

My 7th grade home group teacher on the first day of school introduced us to 'Eric Carle', a plush toy of a caterpillar, and said 'that if any harm became of Eric, he would toss the culprit into the school pool.' Well, he kept his word, as a couple of weeks ago my friend Henry was throwing Eric around the room while the teacher was absent, and was very disappointed to find that two of Eric's feet and his head had been removed. He then proceeded to throw Henry into the pool in FULL SCHOOL UNIFORM, including $240 blazer, and was in a bad mood for the rest of the day. Except we weren't, as Henry's wet demise was quite laughable.

this is one of the things i missed from public school... im home schooled

My grade 5-6 science teacher did youtube videos, just to do experiments so everyone could see them. She was trying to do something with a balloon, and it didn't work, so she placed it behind her. Then randomly 'BANG' the balloon popped and she made a funny sound. I felt bad for her, but it was halarious

My band teacher said Swaggalious XD

So
many
stories!! O__O

Honestly not even going to try listing them all.

I have this one teacher who says stuff like sugar pops instead of swearing XD

Once a teacher I liked called this really annoying kid a smart a**

We were looking at a map and she asked what the place was and he said a map.

Thats why.

"Ooop here I go"
*Falls out of chair*

Okay, so the classrooms at my school have a PA system.

My Language Arts teacher spilled over her coffee and swore. It was great.

Oh my, my teacher says some funny stuff. She's had a text file on the board with a students name saying "Nick, go to the O" and then she'd slowly fill in the "ffice" part every time he did something bad. She nicknamed students, like "skippy", "cocoa" and stuff like that.

Well... I know I've said some dumb things in class before(teach 6th grade science) but one of the funniest things I've heard on intercom was "Ask not what your friends can do for you, ask what you can do for your friends. By Mahatma Ghandi".

Once my teacher was randomly singing a rhyming song with peoples names in the class and it was just taking to first sound of their name and replacing it, and one of the things that was replaced in the song was it was an M replaced with a B in my friend Mitch's name..... and you know the rest (it was the B-word)

My English teacher once pronounced "agape" as "a-gaaa-pei".

Too many to count.
Off-topic-I swear there was another post here before...

my teacher told us if we didn't stop talking she would set us all on fire and we kept laughing...and then she pulled out a jar labeled "Ashes of Obnoxious Teenagers".

"No we don't walk on walls in this school"
