On another of his "no witchcraft" kicks, Darrin wants nothing to do with the magical cigarette lighter given to him as a birthday present by Samantha's father, Maurice. His feelings hurt, Maurice pays Darrin back for his stubborness by transforming him into a mule. This metamorphosis coincides with Gladys Kravitz's strident efforts to clean up zoning violations in the neighborhood -- beginning with the "unsanitary" mule in the Stephenses' living room. Written by Michael Morris, "Daddy Does His Thing" first aired on April 3, 1969. ~ Hal Erickson, Rovi
