When Billy's mother realizes that Mandy has become an eternal houseguest, Mandy returns home. But her own parents can't deal with her and they hire a nanny bent in shaping her into a proper young girl.


At Billy's house, Gladys calls for Harold, Billy and Mandy to report to dinner, but refuses. Gladys' insane temper triggers and she wrecks her husband with a chainsaw, forcing the trio to report to dinner. She, however, excuses Mandy due to realizing that she is an eternal houseguest and constantly remarks as she is not part of the family. She returns home, with her parents terrified and are so scared of her. When she demands dinner, they had enough of Mandy pushing them around and decide to call a nanny to help them. The nanny does everything she can to get Mandy's family to stand up for themselves, but Mandy is too ruthless and mean to stand up to. Grim decides to intervene by making Mandy's parents assertive, but sadly, even then, Mandy wins explaining the town is under her control and that she is only letting the Nanny live here before ordering her minions to capture the Nanny.


  • The plot is a reference to the ABC TV show Supernanny, as lampshaded by Grim at one point.
  • The title is a reference to Mary Poppins.
  • The movie Total Recall is referenced when Harold is shocked upon "learning" that Mandy isn't his daughter, prompting him to get paranoid and question the reality that surrounds him, asking: "Is this all part of some interplanetary conspiracy to make me think I'm a lowly construction worker?!"
  • Mandy's parents plan a second honeymoon to the "Gilligan Islands", which is a nod to the '60s sitcom Gilligan's Island.
  • Mandy magically being in charge of her family could be a reference to The Twilight Zone episode "It's A Good Life", where a young boy controls his family with unnatural powers.
  • Mandy regains control of her parents from Grim's magic by telling them what they want to do and making a hand motion which is a reference to the Jedi mind trick in the Star Wars movies.
  • In Sickly Sweet, Mandy couldn't pronounce the word "please" without it being clear. But in Scary Poppins, Mandy says "Okay, go suck a lemon, please" without any problems.
    • (Response: She had to say it nicely. But in this episode, she said it to be rude.)
  • Credits Scene: Mandy and the nanny are later shown arguing.
