The Nanny-in-Law

Mr. Sheffield's childhood nanny (guest star Cloris Leachman) comes to town. Maxwell recalls how strict she was, and fears that she will dislike Fran. His guess proves correct, and she quickly assumes power over the children, making them dress alike and work on strict schedules. When Fran reveals that her methods make the children happy, though, Maxwell's nanny realizes that Fran might be the best kind of caretaker.
