i had a teacher who turned out to be a paedophile and he had profiles on me and all my class mates. apparently the police used the profiles as evidence to prosecute him...
I have an old hippy professor who did parrot impressions in the middle of a lecture once.
My english teacher last week, while trying to describe the Miller from The Miller's Tale (chaucer) decided to run head first into the classroom door to show how the Miller would have knocked it down with his head...
one of my old tutors at college use to make up loads of stories where she saved peoples lives and was held hostage by rebel forces and oh yeah, the time she stepped on a gorillas head
I have one now, wouldn't say he's strange its more funny but he's always doing david brent/alan partridge impressions and teaches how they would
All of my teachers were strange - I went to a Catholic School.
But the strangest teacher I ever had was...myself. For various reasons I had to resort to auto-didacticism to get myelf through GCSEs.
I had a lot of strange teachers at my old school. What was strange about them was that they seemed absolutely incapable of teaching. Or, in fact, controlling the class at all. Some of them barely spoke English. Some only lasted one day. Many of the broke down crying after just a few hours.
Probably the strangest though was my brother's music teacher who was always convinced that he was teaching physics.
History Teacher - sings random Irish jigs (dances and all) and acts like a dog when she gets annoyed (ie growling and barking at you)
Geography teacher - is about 12 and has random spurts where he talks in stupid voices about absolute crap. that and we seem to know every detail of his personal life - girlfriend, money etc
Chemistry teacher - the usual crazy scientist type. crazy.
Biology - evil woman who has the capacity to annoy everyone in the classroom. and forgets entire arguments with her from previous lessons. evil dammit.
My graphics teacher is notorious for losing coursework, so when i refused to hand it in he offered me his watch to keep until he gave my work back. I didn't hand it in on the basis that i already had a watch!
I had a History teacher who re-enacted the whole of the assasination of Archduke Franz Ferdinand! That was one weird lesson.
someone i know in physics class got called a dense fruitcake by the teacher...
also, my old physics teacher (sec school) was a biology teacher in disguise...
