Worst thing you did you your teachers!

[Loriycs]

We locked our cookery teacher in the cuboard once, she was crying when we let her out!

[ellceeell]

we lit a joss stick and balanced it on top of the blackboard before the R.E. teacher came in, then swore we couldn't smell anything - she kept sniffing the whole lesson!

[mrz]

We moved all the chairs and desks into the corridor while he was reading aloud at the front of the class. When he looked up there was a totally empty room

We locked our french teacher in the cupboard, flicked ink at his shirt to see if he wore his shirt more than once, used to leave condoms all over his class, we'd all say things to him about him 'coming on to us' (which he didn't, we used to say things like 'sir, stop looking down my top) and used to write in his diary detailed accounts of him and his wife having sex.
I wish I'd have known then that he was in the middle of a divorce as she and left him, he ended up having a nervous breakdown and two years later was spotted working in Iceland.

we used to find our teachers in the phone directory and call them and blow raspberries/ whistles down the phone that sort of thing.

Not me, but a friend of mine - he had a teacher who used to write really quickly on the board & rub out the writing with his other hand as he went along (apparently to encourage the class to write quicker)
My friend drilled a hole in the end of a piece of chalk, sank a match (non-safety type)into the end & left it on the board ledge - when the teacher started to write, the chalk exploded....

[Loriycs]

the teachers all drank tea in the classrooms back then and we used to drop things in the tea when they wernt looking.i once dropped pencil shavings in DOH!!

In music class, we were learning a xylophone piece. The entire class loosened the ends off the beaters.
As the teacher counted us in. 1, 2, 3....we all flicked our beaters and pelted the teacher with the little plastic balls off the end.
...another teacher who had a breakdown i will add.

also, chalk all over the white keys of the piano was amusing too.

[Elkat]

With one teacher, we kept a book and took bets on how quickly we could get her to cry... She was also locked in her cupboard on lots of occasions. I learnt a lot from her... particularly never to walk into a cupboard without keeping your hand on the doorframe at all times. Golden rule in teaching (and I have never been locked into a cupboard )

[branflake81]

We had a really doddery old Music teacher who smelled of alchol. We replaced all the chalk in the classroom with tampons (all girls school) . So cruel.

[mynameis]

Unscrewed all the screws on the Geography teachers desk and balanced the table back on the legs. She was always perching on the edge of the desk. We all sat holding our breath through the lesson but the darn thing didn't collapse until her next lesson with a traumatised bunch of first years.

One of those times when the whole class had been shushed but I couldn't stop giggling, teacher (young, quite cool and hip, down wit' the kids type) asked what was so funny, so I told him.

I'm not going to say what it was on here for fear of being banished from MN, but it was very funny, and I have never seen anyone go as red as he did....

[NatalieJaneIsPregnantAgain]

Should add, it isn't funny now, just at the time to a classroom full of 14/15 year olds!

[flatmouse]

We put fairy liquid on outside door handle of classroom - one of those handles that were a round ball and you had to turn it and then push door. Deputy head thought it quite funny at first (was april fool) but not when we refused to open it for the entire lesson!

[misselizabethbennett]

Not really the worst thing, but my personal favourite:

We had French in a lecture theatre with tiered rows of chairs and no windows. We'd get there before the teacher and line up all the chairs on the back row, which the whole class would then sit on (a bit of a squash!). Then one kid would go down and turn the lights off, and we'd all sit there in the pitch black until the teacher came in.

We thought it was piss funny.

Oh, and there was regular humming in all our classes, but I think we all did that didn't we?

[Dragonbutter]

oh yes, humming, that's a classic.

[notcitrus]

We managed the mysterious humming noise once - new wannabe-strict teacher nearly went spare searching in the corridor and round the room for the source.
Best one was when we had a BBC Micro in the corner of the room, but we played too many games when we weren;t supposed to and the teacher disconnected it. Or rather, took the monitor lead away. Which didn't prevent me programming it to make some terrible loud sounds after a 15-minute pause...and the teacher was convinced it couldn't be the computer, because it was Disconnected!

Feel guilty about taking the piss out of the chemistry teacher with a lisp when he came to tell my class to shut up "Oh thir, you're tho thweet..." poor chap started crying. But he's still there and well-respected.

Gormless Latin teacher we just threw stuff at when she wasn't looking.

[Loriycs]

we did the humming thing too, and we all tried to be last one to cough strangely when it went silent in assembly.We thought that was hysterical at 13!

[dilbertina]

We used to see how many bull-dog clips we could put on the back of the physics teachers white lab coat before he noticed. Plus half the class would spend every practical lesson trying to cause small explosion/fire. The physics lab burnt down a few years later so I suspect that tradition was continued.....

He was usch a sweet little man - I do wish we hadn't been so mean, he was always so concerned that his carefully planned experiments kept going wrong.

[Loriycs]

we set the fire extinguisher off in a moblie classroom once and completely drenched it. our teacher came back and really started shouting at us then and she had an asthma attack. We felt really guilty then.
