Who caused the Great Power Blackout on November 9, 1965? According to this episode of Bewitched, the culprit may well have been dear old Aunt Clara. It seems that Clara was in a deep blue funk because her warlock boyfriend, Ocky (Reginald Owen), left her for a younger woman. And when Clara suffers, everybody suffers. Scripted by Ed Jurist from a story by Lee Erwin, "The Short Happy Circuit of Aunt Clara" first aired on November 10, 1966, on the occasion of the infamous Blackout's first anniversary.
