Bell Book and Candle was another romantic comedy about a modern-day witch and a mortal who fall in love.

I remember the episode when Mrs. Bellows (Dr. Bellow’s wife) discovered Jeannie, in full harem girl outfit. Mrs. Bellows immediately presumed that (1) Jeannie and Nelson were secretly married, and (2) That Nelson was keeping Jeannie in an abusive relationship. Mrs. Bellows’ advice to Jeannie was “you need a divorce!”
