Kindergarten Teacher (The Simpsons)

The Kindergarten teacher was Bart and Milhouse's Kindergarten Teacher in Lisa's Sax, the third episode of Season Nine of the Simpsons

She is or was arguably the worst teacher in all of Springfield, even more so than Edna Krabapple or Miss Hoover. When a then five-year old Bart started his first day at school, she noticed he had a little trouble with the alphabet and instead of trying to help him, she told him she expected him to get a lot of F's and then fail in life.

She made him so miserable that Bart drew a very depressing picture of him stabbed in the back with knives, disturbing his mother and terrifying Homer.

Bart became cheerful when he made Milhouse laugh and spit out soy milk. Once told by Milhouse that the world loves a clown, caused him to become the troublemaker he is known to us today as acting out was his only way to get a teacher's attention. Thus she is the reason why Bart acts out in school.

Though she had one appearance she could be one of the most horrible people to appear in the series as she had made a five-year so miserable that he wanted to die. She hasn't made an appearance but it has been hinted she quit and joined the army.
