Elizabeth Taylor has the distinction of making two guest appearances on The Simpsons, both during the show’s fourth season. Her first appearance was in the episode Lisa’s First Word, in which the family is trying to coach Maggie into saying her first word, which leads to Marge and Homer telling the story of Lisa’s first word. In the end, Maggie does finally say her first word, although it’s said when nobody else is around.
Elizabeth Taylor agreed to provide the voice for the famously non-verbal Maggie’s first word. Although her part only consisted of a single word, it was a role that had its challenges. In the DVD commentary for this episode, some of the show’s staffers talked about how it took a few tries for Taylor to get the voice just right. Her initial takes of the word sounded too vampy for a baby. But in the end, she got it just right and played a role in one of the most genuinely endearing moments of the series.
Elizabeth Taylor returned for the season 4 finale episode, Krusty Gets Kancelled, playing herself this time. When Krusty the Clown’s show gets cancelled because all of his viewers start turning into a rival show, Bart and Lisa help him get back on his feet. When they discover Krusty has lots of connections to big entertainment stars like Bette Midler, Hugh Hefner, and Elizabeth Taylor, Bart and Lisa start organizing an all-star TV extravaganza. When they approach Elizabeth Taylor’s agent, he turns it down and she’s okay with that.
But as she watches the special on TV (while polishing one of her big diamond rings, naturally) she regrets not getting in on it and decides to fire that agent.
