was consciously a parody of the humor style of The Simpsons, but the producers felt that it was not funny. As a result, it was replaced by the "Amendment to Be" cartoon, which is a parody of the "I'm Just a Bill" segment of the educational television series Schoolhouse Rock. Worried about potential lawsuits, the lawyer of The Simpsons made the animators change the design of the senator in the segment. Weinstein did the voice of the "Curly amendment" in the segment, claiming the other voice actors "couldn't do it exactly right." The end of the episode features Lester and Eliza, who save Itchy & Scratchy Studios. Bart and Lisa typically solve problems in the show, but the writers decided to try something different and have a new pair of characters take their positions.

He refused to wear the earphones supplied to him in the recording studio, saying they hurt his ears, so he was unable to hear Weinstein from his booth. Cartwright directed Douglas, who was in a hurry and said that he would do two takes per line at the most. However, despite reading his lines all at once, he only had trouble with one scene; the scene in which Lampwick tells Bart he created Itchy & Scratchy required three takes, as Douglas continuously misread the line "I changed all that" as "I charged all that". Cartwright managed to get him to do a third reading of the line by pretending to sneeze during his second take. In his script, Swartzwelder randomly paired David Brinkley and Suzanne Somers together as the
