Trivia: The Simpsons S4E10 "Lisa's First Word"
- Stunt Casting: In perhaps the biggest example of this in Simpsons history, Elizabeth Taylor as the voice of Maggie. (Taylor returns at the end of Season 4 as herself in "Krusty Gets Kancelled", and gets two lines in that episode.) The writers soon regretted this as they spent hours trying to get Taylor to say, "Daddy" like a one-year-old child and not a 20-to-30 year old seductress.
- Throw It In: Homer's line, "Bart can kiss my hairy, yellow butt" after Marge worries that Bart will be jealous of Lisa was ad-libbed (and almost didn't get used as the censors thought the line would be construed as pedophilic, when really to tell someone to "kiss your butt [or ass]" is used as a rude brush-off, not a sexual come-on).
