Bewitched - Season 3 Episode 18
Ho Ho, the Clown

Samantha and Endora take Tabitha to a taping of Ho Ho, the Clown, where Darrins 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 Darrins job and causes the show to be cancelled if they dont do something soon. Samantha comes up with a terrific plan: Tabithas appearance on the show was a publicity stint for a new Tabitha doll.
