A lot of Brady Bunch references were made in this episode.
The kids and the parents are Brady Bunch-esque.
The housekeeper Beatrice is a parody of Alice the Housekeeper.
The music number and the art style parodies the 70s cartoon based on the Bradies.
Each aspect of the episode have the kids learn a moral lesson (some ridiculous).
In fact, the dad was called Mr. B by Beatrice and the two oldest kids were Greg and Martha.
