Bea Arthur said this episode was her most favorite of the series.
Walter asks Maude "Do you love me?" Maude answers, "What is this "Fiddler on the Roof?" Bea Arthur played Yente (the matchmaker) in "Fiddler on the Roof" on Broadway.
We learn that Maude's undergraduate degree is in Romance languages (e.g., French, Italian, Spanish, etc.), which she has never put to use since she has spent most of her post-university life being Mrs. Whoever, an extension of her husband du jour, which is the crux of the episode.
