When Aunt Clara is researching the Book of Spells on people who are cursed, she finds Adam Newlarkin listed between the New York Mets and Richard Nixon. While the fledgling baseball team and failed presidential and gubernatorial contender were jokes in 1965, by the decade's end one would be the World Series victor and the other president of the United States. However, Richard Nixon would resign as President in 1974, because of the Watergate Scandal, so the writers of "Bewitched" were prescient about his fate.

This episode was filmed on June 4, 1965, during the fifth month of Elizabeth Montgomery's real life pregnancy. That baby, Robert Asher, would be born on October 5, 1965.
