Lisa's First Word/References

Trivia

 * Lisa's birthday was revealed in this episode. However, it is not exact. The date isn't mentioned, but it's the last day of the Olympics when Marge goes into labor. Therefore, it would be around August 24, 1983.


 * Bart's first words were also revealed in this episode: "¡Ay, Caramba!" He said that after seeing his parents having sex.


 * Bart's term of "Can't sleep, clown will eat me" was later used as a line in an Alice Cooper song. It has since become somewhat of a slang term to describe insomnia.


 * When Bart is packing his toys up he is saying something, but it's not audible.


 * Maggie said her first word in this episode. Although no one hears her say it because it's her bedtime, the family has presumed Maggie has spoken her first word a few times in "Home Sweet Homediddly-Dum-Doodily" and "Coming to Homerica."
 * However, she literally talks in Flaming Moe's


 * The Krusty Burger scratch & win cards were inspired by a promotional game McDonald's did for the 1984 Olympics where an event would be revealed and prizes would be awarded dependent on whether Team USA scored a gold, silver, or bronze medal. Prizes ranged from free McDonald's food to a $10,000 cash prize. McDonald's lost millions of dollars paying out prizes on that promotion.
 * The footage of Homer building Bart's clown bed was recycled from him building his Wonderbat in Homer at the Bat.
 * Whilst Marge is doing a flashback, some women mention the TV show M*A*S*H. One woman says she misses Klinger, a man who dressed as a lady to get out of the war, another woman says she loved one of the other men.
 * This episode can prove Lisa was a very smart baby.

Goofs

 * Even though it is obvious Grandpa is a younger man in 1983, a picture of his elderly self hangs in the wall of his house. This episode was only set 8 years ago, not much can change of a physical appearance in that time.
 * The unicycling jugglers in the couch gag wear orange shirts when they first appear, but when they go into the background, they are wearing green shirts.


 * In the 1990 episode "Krusty Gets Busted," Krusty says he is (and always has been) illiterate. In this episode, Krusty can read a wire communique about the Soviet boycott. (He could be functionally illiterate, in that he can read something, but not know the deeper meaning of what's being read, but "Krusty Gets Busted" makes it clear that Krusty is a garden-variety illiterate).


 * Sideshow Bob is in this episode, but he has turquoise colored hair.


 * In one scene Todd Flanders has black hair.
 * Todd Flanders is the same age as Lisa (8) and yet in this episode he is approximately the same age as Bart (2 in the episode, 10 in modern day). In fact, Marge is still pregnant with Lisa making a talking Todd impossible. Even accounting for the error of misnaming Rod (12), it's still an age error since Rod is 2 years Bart's senior.
