S03E18: Ho Ho, the Clown

Samantha and Endora take Tabitha to a taping of Ho Ho, the Clown, where Darrin's newest client, Solow Toys, is the sponsor. Because Tabitha is related to Darrin, she is prohibited from the contests. Endora does something about that and makes Ho Ho fall in love with Tabitha and gives her all the prizes. This jeopardizes both Darrin's job and causes the show to be cancelled if they don't do something soon. Samantha comes up with a terrific plan: Tabitha's appearance on the show was a publicity stint for a new Tabitha doll.
