Endora just won't give up her efforts to cause a rift in the matrimonial bonds between her daughter, Samantha, and that goofy mortal Darrin. This time around, Endora insists that Janine (Lisa Seagram), a beauty contest winner hired for Darrin's latest ad campaign, will ultimately break up Sam's marriage. Sam pooh-poohs this notion, unaware that Endora has already used witchcraft to prove that Darrin is capable of infidelity. Written by Jack Sher, "It Takes One to No One" was first telecast on November 26, 1964. ~ Hal Erickson, Rovi
