Supposedly Good TV Teachers Who Are Actually Horrible Educators

Mr. Schue may run one hell of a glee club, but he is not a good teacher in any sense of the word. First of all, he is supposed to be a Spanish teacher, as well as the head of Glee's titular extracurricular. But showrunners reveal in one episode he actually doesn't know Spanish very well at all and has to take remedial classes to receive tenure.

In addition, as the leader of the show choir, he blackmails Finn into joining the group by putting drugs in his locker. Like Walter White, Mr. Schue is nursing his own failed dreams. He once wanted to be a performer, but the need to make ends meet sidelined him into teaching.

Mrs. Krabappel from The Simpsons may show up to work every day and be a constant in the lives of her fourth-grade students, but her teaching skills leave a lot to be desired. Voiced by the late, great Marcia Wallace, Edna Krabappel does little more than go through the motions. She's a not-so-secret alcoholic, she sometimes smokes in the classroom, and she's ready to pounce on any eligible man in a 100-mile radius. She also has an on-again, off-again affair with the school principal.

It's no surprise Mrs. Krabappel has nonexistent boundaries with her students and often pulls Bart into her schemes. In one episode, Mrs. Krabappel and Principal Skinner are under the impression that Bart is the only one who knows about their affair, and they force him to relay notes and messages back and forth between them during the school day.

Annalise Keating from How to Get Away With Murder is an exercise in how not to be a university professor. She's always embroiled in various crimes, including murder. During her lectures, she encourages her students to utilize underhanded tactics and less-than-ethical strategies to win cases.

Then there's that whole favoritism thing. She clearly has a small cabal of students who are her preferred pupils. If you're not among this elite group, she will more than likely ignore you. Also, the drama never ends with Professor Keating; as soon as one crime is solved, she's dragging her students into another one.

It's safe to say Walter White of Breaking Bad likely inspired no one to become a teacher. White uses his chemistry skills to cook up Grade A meth to pay for his cancer treatments - not exactly a glowing recommendation for the teaching profession. In fact, he is deeply resentful about having to be a teacher at all - he originally wanted to be a famous chemist after working on a Nobel Prize-winning research team in graduate school. During the show, he ropes his former student Jesse Pinkman into his schemes, which become increasingly more criminal and dangerous as the series goes on.

Even as a teacher and mentor figure to Jesse, White is inept: "Walt failed as Jesse's teacher because he could never for a moment stop playing the stultifying schoolmaster, the one who insists upon his superior intelligence [and] demands recognition of that superiority from his students," political scientist Samuel Chambers observed. "Only a bad teacher tries to establish mastery by way of [an] assertion of superior intelligence."

Peggy Hill from King of the Hill is a working substitute Spanish teacher in the Arlen, TX, school system. Ask anyone in town - especially Peggy herself, who has no shortage of confidence - the name of a smart and reliable sub, and they would all say Peggy Hill.

It's baffling considering she is downright awful at Spanish. Her butchery of the language makes Mr. Schue look like a native speaker.

Mr. Racine is a substitute English teacher on the legendary '90s teen-angst drama My So-Called Life. He's meant to come off as charismatic and unorthodox, but he's really just a jerk. It's no wonder he comes and goes pretty quickly at Liberty High School.

In one episode, the students hand in their poetry submissions for the school's literary magazine. Mr. Racine proceeds to throw the submissions out the window. He calls the students' work "cutesy, banal, synthetic, appalling." Way to be supportive, Vic.
