Other mistake: Pretending to be Max's assistant, Fran dials a number for Bernadette Peters. The conversation is on speaker phone. The assistant says "one moment please." Niles and Fran continue talking and Maxwell comes in. Fran and Niles sheepishly hurry out of the room. Notice how, this whole time, Fran never touched the phone again to turn the phone off. So Max would hear Bernadette Peters and actually figure out Niles and Fran's plan before the episode's even halfway over.

Brighton Sheffield: Yeah, it just so happens that your voice carries.
Fran: To your bedroom?
Brighton Sheffield: To Michigan.
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.
