"Lisa's First Word" is the tenth episode of the fourth season of the American animated television series The Simpsons.

The story flashes back to 1983, when Homer, Marge, and Bart lived in an apartment on the Lower East Side of Springfield.

[6][7] As the flashback begins in 1983, a young Homer strolls down the street, singing Cyndi Lauper's song "Girls Just Want to Have Fun", which was released that year.

[8] The idea for this sequence came from animation director Chuck Sheetz, who suggested it because the length of the final version of the episode was too short.

[9] Maggie's first word was provided by the Academy Award-winning actress Elizabeth Taylor, who would also voice herself in the season four finale, "Krusty Gets Kancelled".

[10] Although it was only one word, the voice came out "too sexy" and Taylor had to record the part numerous times before the producers were satisfied and thought it sounded like a baby.

[13] Groening recounted this event on a 1994 appearance on Late Night with Conan O'Brien,[14] and was also quoted by the New York Daily News in 2007 as saying "We did 24 takes, but they were always too sexual.

"[18] Nancy Cartwright also mentions the incident in her book My Life as a 10-Year-Old Boy, but states Taylor jokingly ad-libbed "fuck you Daddy" as an initial sound check for Sam Simon.

[1] Marge sets the scene for her story of Lisa's first word with references to the 1981 arcade video game Ms. Pac-Man and the American actor Joe Piscopo.

McDonald's lost millions on the promotion due to the 1984 Summer Olympics boycott by the Soviet Union, as happened to Krusty.

Warren Martyn and Adrian Wood, the authors of the book I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide, said the episode is a "convincing portrait of young marriage and hardship in the days of Reaganomics—and the biggest name to guest voice gets the littlest, but the most significant, to say".

[25] The Orlando Sentinel's Gregory Hardy named it the fourteenth best episode of the show with a sports theme (the Olympics in this case).

[8] He added that "it is probably no surprise that the casting of Elizabeth Taylor as the voice for baby Maggie Simpson's first word was a publicity stunt [...] No mind, the episode in question delivered well-rounded view of series' multiple attractions.

[30] Inspired by an event in The Simpsons writer Mike Reiss' childhood,[6][7] young Bart does not want to give up sleeping in the crib to make way for his newborn sister.

However, because of Homer's poor handicraft skills, the bed takes on an ominous appearance and frightens Bart, especially in his darkened bedroom.

The next morning, Bart is curled up into the fetal position on the floor next to the sofa downstairs, repeatedly uttering the phrase "can't sleep, clown will eat me..." The line inspired the Alice Cooper song "Can't Sleep, Clowns Will Eat Me" from the 2001 album Dragontown.

Bart finds himself bored at the Flanders' house and wants to go home, but quickly changes his mind when he sees the clown bed in his bedroom window.

[33] Other episodes included in the collection set were "Simpsons Roasting on an Open Fire", "Sweet Seymour Skinner's Baadasssss Song", "Trash of the Titans", and "Bart Gets an 'F'".
