Trivia: Although it was kept a secret for years, the part of Thing was performed by Ted Cassidy. He sometimes had to travel to the studio to do it, even if Lurch wasn't in the episode. Though in a few episodes, where both Lurch and Thing appeared in the same shot, assistant director Jack Voglin performed the part of Thing.
Trivia: Although everybody knows all of the Addams Family members' names, none of them had their now-familiar names when Charles Addams created them for the New Yorker magazine. It was when the idea was pitched to the television executives that the names were created. Coincidentally, the Addams Family and The Munsters debuted the same week, and were cancelled the same week two years later.
Trivia: Producer Nat Perrin created the voice of Cousin Itt by reciting gibberish into a tape recorder and then playing it back at a higher speed.
Trivia: Throughout the various television treatments and feature films over many decades, the Addams Family storyline frequently concerned the family's fabulous and mysterious fortune, which was always the target of nefarious (and doomed) flim-flam schemes. However, it was almost never explained how the Addams Family obtained their incredible riches. In this episode from the original TV series, Gomez and Morticia finally revealed the diverse sources of their wealth: Gomez cites his mango plantation, "Mangoes Incorporated"; his Mozambique crocodile farm, "Crocodiles Unlimited"; his Himalayan tapioca mines on Mount Everest, "Tapioca Limited"; and Morticia additionally mentions "Amalgamated Swamp" and his buzzard farm.
