This professor gently explains how businesses establishing their own rules is not, in fact, the same as the Holocaust.

Short and sweet, this teacher reminds their student that he alone is accountable for his poor academic performance.

The teacher keeps it real by reminding this guy if you're planning to cheat, maybe don't let the teacher know ahead of time?

This is one of the longer murders, but we live for the professor who bluntly tells a student that he needs to get his sh*t together.

A student learns the hard way that he has a very, VERY different definition of "research paper" than his teacher does.

Overall, this is one of the more methodical murders. The professor walks this guy through how he better know his stuff before calling the prof out...moments before proving that the student does not, in fact, know what he is talking about.

This prof has practically begged his worst student to come to office hours, but the student decided to just publicly whine about his grade instead.

The teacher didn't have to be this savage, but we love that he just came down on this student from the top rope for no reason.

Lots of teachers gently tell students that it is not the teacher who "gives" a grade but the student who "earns" the grade. This professor cut right to the chase and said "you fail me" to someone talking sh*t online.

Part of being a good teacher is understanding both that words mean things and the basic history of major subjects. Here, a teacher walks a student spouting bumper sticker politics through all of the benefits that he has due to "socialism."

You know when the class message STARTS with the professor calling the class a "cesspool" that this is going to get pretty damn rough.

And there it is: a teacher savagely reminding her student that he can just Google for additional assistance instead of just playing a victim online.

They say that you can't really understand tone through text. But reading this, you can 100% hear this prof talking down to one of his idiot students like he would talk to a small child.

Why use many word when few word do trick? This teacher only needed two sentences to tell this student that they pretty regularly sucked in class.

It's kind of a jerk move treating retail work like it is some kind of inherently bad thing. But we had to laugh at this guy coming for his former student so hard basically out of nowhere.

Many students like to think their teachers will remember them many years down the line. But as this teacher vividly explains, the only ones a teacher is super likely to remember are the terrible students!

Play stupid games, win stupid prizes! This student tried to stunt on his teacher only for the teacher to point out that he hasn't uploaded his actual work. Naturally, the teacher decided to treat the student like the idiot child he is.

This response is fun because it starts out as a philosophical meditation on our place in the world and how life goes on all around us. Soon, though, the teacher sums up his feelings in two words that every student needs to hear: "STOP WHINGING!"

If you thought teachers were savage to their own students, you should see how they treat each other! This Catholic education organization tried to tell a Cincinnati Teachers group how to conduct themselves online. The teachers treated this like any other student asking a dumb question online and pointed out the extreme hypocrisy of worrying about online conduct instead of the rampant pedophilia in their own organization.

This student asked the seemingly innocent question so many students ask: "did I miss anything important?" But as this wildly savage teacher explains, the very question assumes that much of any given class day must be unimportant and that even asking the question is rude as hell.
