Because Erin Murphy was ill, her sister Diane Murphy played Tabitha in this episode. The girls were fraternal twins and looked a good deal alike when they were younger, so they could alternate playing Tabitha. But at this point in their lives, they no longer resembled each other as they once did - and viewers noticed. Reportedly, the producers received a lot of letters asking "Who was that girl?"
Uncharacteristically for a sitcom of the era, this was filmed almost entirely outdoors.

The boy who sees Tabitha go UP the slide and runs away was played by Teddy Quinn who, nine months earlier, was the spoiled little boy that Tabitha changed into a bulldog.
