The Simpsons

If the audio commentary is true on that episode, and I’m actually remembering correctly. Wasn’t she supposed to have said “Fuck you daddy” on one of the readings?

Ok Had to look it up

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".[4] While promoting the episode, the producers initially did not reveal who the voice of Maggie would be, prompting speculation as to the identity of the actress.[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.[11][12] Several sources, including John Ortved's The Simpsons history article "Simpsons Family Values" in Vanity Fair, have reported that after Taylor had been made to repeatedly record the line, she said "fuck you" to series creator Matt Groening and stormed out of the studio.[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. Finally, Liz said, 'F— you,' and walked out."[11]However, Groening later denied the story in the DVD commentary for the episode "Gump Roast",[15] while Jean stated in a piece after Taylor's death in 2011 that Taylor had said "fuck you" in jest and in Maggie's voice and did not storm out.[16][17]Yeardley Smith supports the latter as well, tweeting she "didn't storm out but she did take exception to being asked to say 'Daddy' 20 times & she let us know by saying 'fuck you' when she was done."[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.[19]
