Other mistake: In this episode, Maxwell finds out about Fran's tattoo. Fran mentions that her tattoo was on her behind. Maxwell spends the episode trying to see it but in Season 3 and Episode 26, when the Sheffields are in the beach, Fran strips down to her bikini in front of Maxwell. Maxwell checked her from behind, meaning he should have been able to have seen her tattoo.

Trivia: At the end of the show, Fran and The Gym Teacher, played by Rita Moreno, are discussing Fran's high school boyfriend. Moreno's lines in the scene are from the song "A boy like that" that her character Anita sang in the 1961 movie West Side Story.
Question: What does she even do? The kids are too old for a nanny.
Answer: Mr. Sheffield needed someone to manage the kids, not necessarily babysit them. Brighton was a Bart Simpson type, Maggie was shy and awkward and Gracie had personality issues.
