Despite being mentioned that she was going through a sex-change operation, Mrs. Pommelhorst is still seen as a woman in later episodes, including the recent episode "Blazed and Confused". Presumably, she decided not to go through with the operation.
In the show's entire 17-year run, this is the very first full-length episode centered around Groundskeeper Willie. He was however, the central character in "Nightmare on Evergreen Terrace", one of the three segments of "Treehouse of Horror VI", and had a large amount of screentime devoted to him in "Girly Edition"—in which his shack was also destroyed by Bart's shenanigans and left him temporarily homeless.
Connections: This episode covers the same topic as "My Fair Lady." This episode is also somewhat similar to the season 11 episode "Pygmoelian", in the sense that it features another secondary character getting a 'makeover' or 'new look', last time it was Moe Szyslak. "My Fair Lady" is also a retelling of Pygmalion.
In the gym teacher's datebook, "Double Bombardment" is listed on Christmas.
The episode was rated TV-PG for drug references, violence, coarse language and sexual references.
In this episode's end credits, instead of the normal music there was a medley of the songs heard.
The man in the commercial sits down and the music stops, but when Homer and Eli Stern VI have stopped talking, he is up again and the music is playing.
The musical is referenced throughout the episode, with Lisa in the role of Professor Higgins and Groundskeeper Willie as Eliza Doolittle.
The episode also features songs similar to the style of the musical.
Coach Krupt's saying "What is your major malfunction, Simpson?" is a reference to Full Metal Jacket. In fact, the entire scene is modeled after a similar scene in the film, from camera angles to Bart's facial expression.
