"Simpsoncalifragilisticexpiala(Annoyed Grunt)cious" (pronounced Simpson-Cali-Fragi-Listic-Expi-Ala-D'Oh-Cious) is the thirteenth episode of the The Simpsons' eighth season.

Plot
When Marge starts losing her hair due to stress, the family hires a nanny to help out at the house. Homer attacks all the applicants since he thinks they're all men in drag, like in Mrs. Doubtfire. A nanny named Shary Bobbins (parody of the fictional nanny Mary Poppins), flies out of the sky with her umbrella, lands at their house and applies for the job. She helps the children with chores and sings songs to them. Once the family starts to behave properly, she leaves, but the family immediately become dysfunctional again, prompting her to return. After a while, she discovers how lazy and useless they are and gets upset. The family explains, in song, that she can't change them and they're happy just the way they are. As she flies off, Lisa wonders if they'll ever see her again. Homer assures her that they will, not noticing that Shary has just been sucked in the jet engine of a plane and shredded into pieces.
