Trivia

 * Hank Azaria, voice of Moe Szyslak, stars in the Broadway musical Spamalot, which was parodied in this episode.
 * During "Stab-A-lot" Marge and Lisa wear different formal clothes than they do in all preceding episodes.
 * When Lisa started to dress like a boy, her waist was round just like Homer's and Bart's. Usually, her waist is like Marge's.
 * In the promos for this episode, the gag where Bart says he can walk around with Bart Jr. hanging out, then pulls out his frog, the frog's subtitled line "I thought he meant his penis" was removed. The subtitle wasn't removed on Global.
