S3, E4: Aunt Clara baby-sits with Tabitha Stephens and Timothy Tate when their parents go to the theatre. She entertains the babies with magic. Peeping through the window, Gladys Kravitz is completely befuddled. Her magic dulled by age, Aunt Clara's spells go awry and suddenly Timothy becomes twins. Aunt Clara can't remember how to undo the spell. Arriving home, Samantha and Darrin are aghast. Frantically, they try to keep the Tates from learning what happened to their baby. Since Larry has to catch an early plane, they persuade the Tates to leave Timothy overnight. The next morning, Louise arrives followed by Larry, whose flight has been delayed.
