In order to reduce the school budget, Principal Skinner decides to put forth "Operation S.L.A.A.M.: So Long Athletics Art and Music".
Upon hearing this, the children of Springfield Elementary go on strike. Joining them in the ranks of protest are other art loving unions throughout Springfield including the police force, Goat Milkers, Hand Models Local 702, & the United Federation of Theme Park Zombies.
In the end, Principal Skinner reinstates the banished programs by doing away with a less popular school necessity, flu shots.
