Samantha gives Darrin a magic amulet, which, when worn, forces Endora to be nice to him. When Endora discovers the source of her uncharacteristic good nature, she spitefully turns the tables on Sam and Darrin. Naturally, this fit of pique occurs just when Darrin is trying to curry favor with his latest client, greeting-card manufacturer Augustus Sunhsine (John Fiedler). Originally telecast on April 9, 1970, "Turn on the Old Charm" was written by Richard Baer. ~ Hal Erickson, Rovi
