alone watching Yentl followed by The Erotic Adventures of Hercules. After returning Bart and Lisa home, Selma wonders how Homer manages to raise kids every day. She decides she can live without children for now and adopts Jub-Jub, Gladys' pet iguana. Production Writer David Stern said he wanted to go back to a "Patty and Selma episode", because it was sustained so well when he wrote "Principal Charming". He thought it was important to "keep these characters (Patty and Selma) alive." The animators had trouble with the size of the characters' pupils during the season. In this episode, they are noticeably larger. When the family watches the video will, Julie Kavner did five voices in the scene. When Great Aunt Gladys shows off her collection of potato chips, the scene was inspired by Myrtle Young, who appeared on The Tonight Show Starring Johnny Carson. During an interview with David Letterman, Young said she was working in quality control at a potato chip factory, and collected potato chips that looked like, amongst other things, famous people. The scene where Homer ate a chip is a reference to the Johnny Carson appearance, where, whilst Young was looking away, Johnny ate a chip from a separate bowl (not of the collection), Young, thinking Johnny had ate a chip from her collection, was shocked, before Johnny cleared up the misunderstanding. Jub-Jub made his debut appearance in this episode; the name of the iguana Jub-Jub came from Conan O'Brien. Though research is usually done when real languages are used on the show, the foreign language heard on Selma's ham radio is fictional. Cultural references The episode title is a take on the 1982 film Sophie's Choice. Marge's flashback of her and her sisters swimming in a lake is based on The Prince of Tides. Later, Homer and Marge watch the movie Yentl, making it the second reference to a movie starring and directed by Barbra Streisand. The singers at Duff Gardens, Hooray for Everything, are a parody of the musical group Up with People. The group is seen performing a kid-friendly version of the Lou Reed song "Walk on the Wild Side". Homer and Bart start to sing "Ding-Dong! The Witch Is Dead" from The Wizard of Oz. The poem that Great Aunt Gladys reads at the start of her video will is "The Road Not Taken" by Robert Frost.
