The episode hosted by Steve Martin featured "auditions" of new acts for the show. It was actually a dumping ground for all of the ideas that hadn't quite formed into coherent scenes. Since there was no "audience", the laugh track wasn't used. Instead, the producers had a few stagehands provide the laughter. Because there is no audience track in this episode, it is thus the only episode in which the closing theme is audible for its entirety; in all other episodes the closing theme is obscured by canned applause and audience laughter.
Mary Louise, Baskerville the Hound and Lenny the Lizard are all identified by name name for the first time. All of them had made appearance in the previous season, with Baskerville dating back to Purina Dog Chow commercials from 1962. Mary Louise's name is still a bit uncertain as she also goes by Carrie Louise and Terry Louise.
In late February, 2021, this episode became one of 18 Muppet Shows to get a content warning on Disney+, for "negative depictions and/or mistreatment of people or cultures".
The name Baskerville The Hound is a reference to Sir Arthur Conan Doyle's 1902 "Sherlock Holmes" crime novel "The Hound of the Baskervilles."
