Is there a teacher who you really hate/hated in school?

I'm just astonished at my luck, compared to most people. I got along with every teacher I ever had. There were some I slightly disliked, or respected only grudgingly, but none I outright hated. Even the ones I hated initially, I eventually grew to like. Maybe it was luck, maybe it was the comparatively small school. (It averaged fifty-five kids per graduating class in those days.)

I once had a crazy cat-obsessed lady as my World Geo/AP Euro teacher for two years. She'd remark things like "If you were half as smart as my cats were..." and other bullshit, as well as be prone to jumping and screaming "MRREEOOOOWWWWW" for no reason just to freak the living daylights out of us. She considered cats to be the ultimate superior race (Like the Egyptians, just more overzealous and jingoistic) and failed me for a semester for saying I'd rather eat fifty dishes of pufferfish than own a cat.

To balance this out, the same year I did have a supremely awesome science teacher who demonstrated the danger of the gas faucets by pulling the lever and lighting a match in front of it.

We put the flames out eventually.

Oh and I forgot, in year 12 my english teacher accused me of getting a uni student to do one of my essays because of the quality of the work. I then pointed out to her that we had done the essay in class and in fact I had to borrow a pen off her because I was so unprepared. She then gave be a B, when I asked her why she just said "You should be happy with the mark you got."

I once had a biology substitute try to convince the class that evolution was wrong. I stood up, laughed in his face and told him that he was infringing upon my rights as a US citizen by forcing me to believe something that was wrong. He got pissed and stopped. I told the real teacher the next day, she laughed and requested the sub be fired from subbing at our school anymore. Never saw that man again.

There was this Drama teacher who was universally regarded as a *****.
Her name was Ms Schaussberger, but being the clever clogs we were it quickly became Sheissberger when she wasn't present

Anyway, she once subbed for our Japanese class. That day we happened to be having a Smash Bros. Tourney in which I was competing, which was taking place during lunch, right after this period. Now since I wasn't going to have a chance to eat at lunch, it makes perfect sense that I'd want to eat beforehand. This makes even more sense in light of the fact that my teachers don't care if we eat in class or not, unless it's a science lab which has to be kept clean. What does she do? She calls me out for eating in class. She tells me to see her after class, and the following dialogue takes place:
"What were you doing?"
"Eating"
"Are you normally allowed to eat in class?"
"Yes"
*She takes a while to regain her composure*
"Well, would you like to talk to about it?"
"Not really" (Keep in mind that it is now lunchtime and if I don't hurry I'll get disqualified from the tourney)
*smug grin* "That's what I thought. Don't do it again"

I'm lucky I only got off with a warning, but it was for something I always do anyway without my real teachers giving a shit. And she threatened me with a trip to the deputy principal's for it!
