There is a series of great comedic events in the series, starting with a series of events where Darren's parents make their first visit to Stevens' house. Darren's mother, Phyllis, hopes to find his wife as a poor housekeeper. Soon after, Samantha smoked Aunt Clara's chimney on an unexpected visit. Darren is concerned about this kind of impression Aunt Clara will give to his parents, but agrees with Samantha that they should feel that Aunt Clara is welcome. On the other hand, Aunt Clara is designed to help Samantha achieve great success with her husband, and uses her magic to prepare a feast for dinner.
For 1964, a conventional suburban comedy with a most unconventional witch in the lead role was inventive, certainly more inventive than a certain Hollywood remake, so you can hardly blame producers for milking Samantha's trademark nose twitch
But despite its focus on Samantha's domestic role, the show does reflect some of the cultural changes of the time. Witches and witchcraft became metaphors for discussing contemporary issues like racial discrimination.
