Freiberger pitched the subplot involving the model rockets in the beginning of the episode . He based it on a real-life experience , in which he , as a child , accidentally launched a model rocket into a window in his house . A scene from this subplot was removed from the episode following the September 11 attacks . The scene would show a man named Hassan Jay Salam being arrested by policemen ( who tells them to call his cousin Casey Kasem ) , who think the rocket Bart and Homer launched was launched by him ( The rocket bears the abbreviation HJS , which stands for Homer J Simpson ) . After the attacks , the scene was considered too offensive by the Fox censors , so the scene was removed . Originally , the subplot would involve Marge trying to get Homer to build model rockets with Bart . Homer would not want to at first , but after Marge convinces him , he would soon get more into it than Bart . The plot idea was encouraged by some of the writers who thought that Marge had " gotten short shrift , " and , according to Freiberger , Marge would have had a " really big part motivating the story " had the subplot remained intact
