Mick
The sassy teacher who all the girls have a crush on and flirt with. He enjoys all the attention.

Keith
The teacher who never makes the class do any work and usually just sleeps. He doesn't care what you do as long as you don't die or kill each other.

Brian
The teacher who is always trying to make class better and more enjoyable, which he is great at, because his class is always fun and all the students love him. Basically he's the teacher that manages to teach and have tons of fun at the same time.

Charlie
The classic straight forward teacher who teaches stuff the way it is without changing it or anything.

Bill
The teacher that no one listens to. No matter what he says all his students take it as a joke and ignore him.
