Matt: I guess you know this house is a Frank Reich?
Mary: A Frank Lloyd Wright?
Matt: Oh, no, no,no. Reich!
Matt: Right. The two were often confused, but, in fact, Frank Reich died in 1936 of acute frustration.
Mary: Phyllis, I didn't say he doesn't want to talk about marriage. I said he doesn't seem to ... want to talk.
Phyllis: Mary, when they don't seem to want to talk, marriage is what they're always not talking about.
Ted: I've heard of that guy.
Murray: Who've you heard of, Ted?
Ted: Frank Lloyd Wright - one of the Wright brothers!
Lou Grant: (speaking to Mary and Murray about his feelings on looking his age) I like the respect that comes from a "well-seasoned" look. In fact, in High School, the teachers called me "sir."
This episode was filmed on September 17, 1971.
Mary's house becomes the subject of talk in this episode when it catches the eye of an architect, who claims it is one of many in Minneapolis that were "poorly made" by an architect named Frank Reich. The house in real life is an 1892 Queen Anne Victorian, built by Edward Stebbins, that was put on the market for $3.6 million in 2007 in Minneapolis. While filming the show, the house was used for outside shots only, while Mary's and Rhoda's apartments were studio sets.
Rhoda: (to Mary) When you're over thirty and not married, there's no such thing as "just dating"...unless you're Gidget.
Rhoda is alluding to the character in the film Gidget that was eventually adapted into the television series Gidget. It featured a young girl, Gidget, who dates her long-time boyfriend, Moondoggie, throughout several movies and then the television series.
