Full Story[]
Bart and his classmates get their cell phones confiscated by Mrs. Krabappel for using them in class constantly. At a meeting in Bart's backyard, the students express frustration about the events of the day and Bart wishes there was a way for their teacher to be more relaxed. During this a drunk Homer is playing with Santa’s Little Helper and the two “switch roles.” Bart realizes that Homer is always fun to be around when he is drunk so the students plan to get Krabappel drunk, in an effort to make her more fun. The students steal some alcohol from their parents and put it in Krabappel's coffee the next day. After Krabappel gets drunk she does act more positive and makes a scene by singing a loud, off-key, incoherent version of "This Old Man" with her students. Even when walking in the hallway they walk in zigzags and have fun. Unfortunately things go downhill when she ends up hitting on Dewey Largo and disrupting an assembly bidding farewell to the foreign exchange students. When Skinner escorts her out, she happily runs from Skinner, Bart starts to think they overdid and while Nelson disagrees at first, he takes it back when Krabappel is on top of a large globe and crashes. Skinner tells Edna that because of these drunken antics she is fired despite her insistence that it was all unintentional. Bart feels bad, so he plans to help Krabappel get back on her feet. Bart and Milhouse buy a book called "The Answer". Following the instructions of the book, Bart and Krabappel build a Muffin store called Edna's Edibles. Then Bart confesses of spiking the coffee with booze and therefore he is responsible for getting her fired. Mrs. Krabappel is furious at Bart and tells him that her real dream was to be a teacher and now she's facing heavy debt as well as a competition from other newly-opened muffin stores. After destroying the self-help book, Mrs Krabappel declares that the only kid she has ever met who is "bad on the inside" is Bart, much to Bart's shock. Meanwhile, at Springfield Elementary, a new teacher called Zachary Vaughn teaches Bart's class and gives everyone their cellphones back, everyone loves him, except Bart. Bart plans to put alcohol in Zachary's energy drink as well but backs out at the last second and chooses to confess to Principal Skinner instead. While he is admitting this, Bart and Skinner hear someone shouting in the hallway. It's Zachary, shouting drunkenly that he hates children. Skinner initially thinks Bart spiked his energy drink and states that he thought Bart told him that he didn't spike it. Zachary confirms Bart's statement, as he has a tendency to spike his own energy drink. Willie takes him away (muttering that it always happens to the good ones as he does so), although not before Zachary attempts to defame the faculty by claiming that they just want to control the students. Krabappel gets her job back, although she does give her revenge to the students for causing her to get fired in the first place by giving them extremely stale muffins.
