Bart commonly appears nude in the show, although in every case only his buttocks are visible. In "The Simpsons Movie" (2007), Bart appears in a sequence where he is skateboarding while fully nude; several different items cover his genitalia, but for a brief moment his penis can be seen. The scene was one of the first worked on for the film, but the producers were nervous about the segment because they thought it would earn the movie an R rating. Despite this, the film was rated PG-13 by the Motion Picture Association of America for "Irreverent Humor Throughout." The scene was later included by "Entertainment Weekly" in their list of "30 Unforgettable Nude Scenes."
