Darrin doesn't want his parents (Mabel Albertson and Robert F. Simon) to find out that baby Tabitha is a witch, but at the same time, he can't come up with a good reason not to leave them alone with their granddaughter. The problem blossoms into a full-scale feud between Darrin's mother and Samantha's mom, Endora. Worse still, the bitter feelings threaten to break up Darrin's mom and dad. Written by James Henerson, "It's Witchcraft" first aired on March 30, 1967. ~ Hal Erickson, Rovi
