- During the scene when Arpa denies knowing her nephew to Lady Madame, Crazy Cousin Gizmo takes off his hat, duplicating his self-portrait that's behind him.

(as the DeFault family reluctantly awaits the unveiling of Robot's newest invention)
Robot: (to Arpa) Mother. (to Grandma) Grandma. (glares at Gart) Evil brother. Thank you for coming tonight.
Arpa: You promised us finger sandwiches.
(after realizing its Crazy Cousin Gizmo who has unexpectedly visited them)
Robot: Aren't you supposed to be in a mental institution?
Crazy Cousin Gizmo: They let me out when I told them I wasn't hearing voices anymore!
Robot: (excited) You're not? That's great!
Crazy Cousin Gizmo: Oh, I still hear them! (whispers) I just don't tell anyone. (laughs) It was Princess Invisible's idea! (points toward 'her')
Monster: She's clever!
Crazy Cousin Gizmo: And rude!(points at 'her' next to the fridge)
