Bernard Fox makes his first Bewitched appearance, but not as his soon-to-be familiar role of Dr. Bombay. Instead, Fox portrays a self-styled "witch debunker" named Osgood Rightmire, who, at a lecture attended by Samantha and Darrin, describes all so-called witches as dull neurotics. Trouble begins a-brewing when Darrin is hired to publicize Rightmire's lecture tour. Adding to the dilemma is an ancient ring in Rightmire's possession -- a ring that has a very strange effect on Sam. Written by Paul David and John L. Greene, "Disappearing Samantha" originally aired on April 7, 1966. ~ Hal Erickson, Rovi
