Reginald Gardiner guest stars as Lord Montdrake, an aging warlock living a lonely existence in his gloomy English castle. Mistakenly believing that Darrin has stolen his servant Elspeth (Hermione Baddeley), the surly Montdrake casts a variety of irksome spells on poor Mr. Stephens. Samantha solves the dilemma when she determines that all Lord Montdrake needs is a little company to brighten his existence. Written by Ron Friedman, "I Get Your Nanny, You My Goat" was originally telecast on December 14, 1967. ~ Hal Erickson, Rovi
