Oh man, do I have teacher stories...Here are a couple:
In 8th Grade there was 1 math teacher that no one wanted to have because there were rumors that he was batshit insane. Usually, teachers get a bad rap and you find out that they aren't so bad after being in their class a while. Well, the first day of class, there were a couple of idiots who couldn't stop playing around and laughing. He warned them once. The second time, he rushed from across the room and threw their desk across the room. They sat there for about a second looking real stupid in their chairs with no desk. He told them to get up or he would toss them with their chairs. The quickly got up and ran to the back of the class. He told them to stand there for the remainder and not say a 1 word or lean against the wall. And they did. Later, the same day, some idiot peaked his head in the class to wave at one of his chums or something. The teacher threw a chalk board eraser fast ball straight at his head. The guy ducked out at the last micro second. The teacher chased after him in the hall, caught him, threw him in the class and sat him next to the fire extinguisher. He told him to stare at and read the fire extinguisher for the remainder of the class and that there would be a quiz after class. If he failed, there would be dire consequences. I laughed.
After a few weeks of his class, you could tell he wasn't so bad. I think he just liked to scare the shit out of his students the first day so there wouldn't be problems afterwards. He was kind and had a decent sense of humor.
In HS 10th grade, we had a history teacher that was totally wacko. I had him in the 9th grade for Law, but I think he lost his mind by the 10th grade. He would say the most retarded and innaccurate history "facts," curse the "white man" and his fat wife every day. Some of his fat wife jokes were hillarious.
He would also turn up the AC up all the way every day. We later found out through a conversation he was having with another teacher that it was because he wanted the girls' nipples to erect. :lol We did have some super hot chix in there.
My senior year, I had a economics with this incredibly annoying chick. She would have an (often incorrect) answer for everything. She thought she was the smartest being on earth. Every day she managed to piss me off with her big mouth. Anyway, one day, she went off on a rant as per usual. After everyone was done rolling their eyes at her, the teacher put some stuff up on the projector. She began to discect it and bitch about the homework, her grades, etc. and the teacher comes back with one of my fav lines of all time: "Wow, looks like somebody had bitch syrup with her attitude pancakes this morning." I laughed my ass off and so did most of the class. Her face turned bright red and she finally shut up for once in the 4 months we were there. It was a classic moment.
