Skinner's elementary school is dilapidated, the bus is in terrible shape, the food is unsatisfactory, etc. Bart sees Krabappel and Skinner arguing about this, so he pushes both their buttons to try to bring about a teacher's strike and cancel school.
Bart is ecstatic, but Lisa is horrified. During the strike, kids have to stay at home with their parents. Bart unleashes his unique brand of mischief on the town. Lisa is worried about becoming stupid and not getting graded, and starts to go insane. Milhouse ends up being tutored.
Bart's plan backfires when substitutes take over the teachers' jobs, including Marge as Bart's teacher, which causes Nelson, Dolph, Kearney, and Jimbo to bully him even more.
Bart gets Skinner and Krabappel to start negotiating again, and they finally come to an agreement. To raise funds for the school, they rent out the school's coat rooms to Springfield's overcrowded prisons.
Feel free to submit a full recap.
