A motorcycle cop tells Darrin (turned into a witch that resembled Tiny Tim): "I am not going to ask you for a chorus of Tiptoe Through the Tulips", the popular song originally published in 1929 and redone by the ukulele-playing singer in 1968.
This episode takes place on October 31, 1969.
The title is based upon the often used quote from Shakespeare's play Hamlet, "To be or not to be."
Endora purposely bungles Darrin's name again: Durwood (5 times), and Dobbin.
