When Marge becomes stressed, the Simpsons hire a nanny, a Mary Poppins parody named Shary Bobbins (voiced by Maggie Roswell).
The episode was directed by Chuck Sheetz and written and executive produced by Al Jean and Mike Reiss.
They are unable to find anyone suitable until a woman glides from the sky with a magical-parrot headed umbrella, introducing herself as Shary Bobbins.
The family begins to treat Shary poorly, and they lose interest in her zest for life and zealous reform.
Realizing the effect the Simpsons have had on Shary, Marge admits that nothing can change them, and the family expresses their contentment with their lives through a song.
[7] While writing, Jean thought that the songs would stretch out and make the episode the proper length but it was considerably shorter than required.
[5] Several additional scenes, such as the full-length opening sequence and the Itchy & Scratchy segment, were added to pad out the episode.
[6][8] Quentin Tarantino was also asked to guest star as himself in the Itchy and Scratchy short, but he did not want to deliver the lines required, believing them to be insulting.
Several of the musical numbers are direct parodies of songs from the film, including "The Perfect Nanny", "The Life I Lead", "A Spoonful of Sugar" and "Feed the Birds"; a deleted scene features Patty and Selma singing their version of "I Love to Laugh".
[5] Homer's imagination is a parody of the dancing characters in Steamboat Willie and features the song "Turkey in the Straw".
Principal Skinner is seen in a short, anachronistically Victorian scene, trying to sell Jimbo Jones in the park ("Boy for sale!").
