When Fred and Barney are served alphabet soup for dinner, Barneys serving has the letters H B on top, a nod to Hanna Barbera.
The title is a spoof of the then-current movie A House Is Not a Home (1964), which was based on Polly Adler's 1953 autobiography.
The underscoring in the final scene was recycled from the music of H-B's concurrently-airing "Jonny Quest."
