The following list of people put a negative connotation to the teaching profession. Popular culture really does a good job at defining the bad but not the good.
1. Ms. Dolores Umbridge, Harry Potter
No one can really top this teacher who raised havoc on her pupils at Hogwarts. Her misbehaving students do not write lines with ink; they wrote them with their blood. She shuns those who do not agree with her and murders those who are not pure blood.
2. Ms. Edna Crabapple, The Simpsons
She is an alcoholic teacher who does not know how to separate her personal life from her job. In one episode, she and the principal kidnap Bart Simpson and hold him hostage to make a point clear to the Superintendent. Who can forget how she was caught making out in the janitor’s closet with the principal by her students? She is a shame to the teaching profession.
3. Mr. Cannon, 90210
This man really is a piece of work. He is a pedophile who prays on teenagers, especially those who are his students. He date raped Erin Silver and raped Naomi Clark, who were both his students. Turns out, he had a colourful past before moving to Beverley Hills as well. In England, he was wanted for the same charges.
4. Ms. Agatha Trunchball, Metilda
This principal is a nightmare. She antagonized her students, beat them and took them by the curls and threw them out the window. She had no connection to her students and all her students feared and hated her.
5. Ms. Elizabeth Halsey, Bad Teacher
