The only episode in the series with no mortals.
With Dick York's medical incident occurring during the filming of the prior show, he does not appear in this show and his only mention occurs when Samantha calls him to tell him about her pregnancy. The focus of this show instead shifts to a squabble between Endora and Maurice.
Abigail was the one of the few witch characters on the series whose first name didn't end with an "a" (or UH sound).
This episode is unique for pre-1970s sitcoms in that it portrays Endora and Maurice in, as Maurice describes to his private secretary, "an informal marriage".
