- Edited for Syndication: In the pilot a Cold Open that featured Mary seeing Rhoda off at the airport is missing in reruns.
- Hey, It's That Guy!: Mr Roper is Ida's doctor.
- Hey, It's That Voice!: Brenda is Marge Simpson, while Carlton is Garfield.
- Throw It In: Co-Producer Lorenzo Music was reading Carlton's lines while actors were tested for other parts interacting with the doorman when it was decided he was the perfect Carlton.
- What Could Have Been: There was almost another Spin-Off in the form of Carlton Your Doorman, which finally gave a face to Carlton... in animated form. MTM's only cartoon (The Duck Factory doesn't count), it never made it past the pilot, which aired as a one-off special in 1980.
