Bart Gets A 'Z'

In the tragic life of Mrs. Krabappel, she wakes up to nothing but a bed filled with tests, exercise she barely manages to do and when coming to school, she has to try and educate all her students, who sit in their chair all texting and playing games on their cell phones. When Krabappel decides to confiscate every student’s phone, Bart decides to do something about the matter, and spikes her coffee with booze, resulting in her making a fool of herself. However, when Principal Skinner sees her joking around, he fires her, giving the class a new, “funkier” teacher.
