Who was the worst teacher you ever had?

My least favorite teacher EVER is my freshman year, second semester, geophysical science teacher. He was one of those teachers that tried to be 'hip' with the students and would make jokes all class instead of teaching the material. Then, he would grade you really hard on labs and such. Plus, it was really hard to tell when he was serious so that was creepy.. Also, he always asked people which hand is their dominant because he loves left-handers and even has a calendar with left-handed See More▼ people facts on it.... We both hated each other because I never laughed at his jokes when everybody else did. I knew he wanted me to laugh because every time he made a joke he would look right at my poker face. The reason I cannot STAND him, though, is that he gave me a zero on a test for LITERALLY NOTHING. He made up a reason and refused to listen to me and was very arrogant, saying that "I should be thanking him for not telling the principal." Somehow I ended up with an A-, but I still hate him.

These are all the stories from my math teacher:
Me: *stands up because it's the "lady week" and I asked to go to the bathroom*
Teacher: Excuse you, why are you leaving my classroom?....you have to go? Too bad, hold it in, you had three minutes to go
Me: Sorry but I don't think I can hold in blood
Teacher: *forces me to sit back down while I'm internally dying*

Class: *screaming, listening to music, on their phones, talking non stop*
Me: *whispering to friend* See More▼
Teacher: *gives me a detention for distracting the class*

Me: *asks a question, saying I don't understand the concept*
Teacher: *yells at me for not paying attention*

Me: *is standing up LEGIT I looked at the clock, three seconds before the bell and gets yelled at*

Me: *is early*
Teacher: *yells at me for wasting his time*

Me: *is a few seconds late*
Teacher: *yells at me for not caring enough to be early*

Me: *doesn't do one page of homework*
Teacher: *takes my paper, goes in front of the class, and shows the class and goes on saying how stupid I am and how you don't want to end up like me*
