in a fantasy land. Jack reluctantly gives in to his wishes; however, upon its unveiling, the new mural is panned by everyone in town. Refusing to admit that he forced Jack to create it in the first place, Skinner instead blames Jack and fires him. Sometime later, the mural is set on fire by a mystery arsonist, and everyone manages to get a look at the real one. Everyone in the school assumes Jack did it to get back at Skinner. While the police are out searching for Jack, Marge finds him hiding in the school playground. He swears to her that he did not start the fire.
