synopsis
Believing that she's been insulted, Endora casts a spell that will turn Darrin into a mouse at midnight unless he apologizes. Samantha tries to head off the hex without violating the rules of witchcraft, and without appearing to break her "no magic" promise to Darrin. Alas, Sam's cure may be worse than the disease. Bernie Kopell, who appeared in the previous week's episode "A Bunny for Tabitha" as a lecherous client, is here cast as the warlock Apothecary. Originally telecast on November 13, 1969, "Samantha's Secret Spell" was written by Ed Jurist.
