Question: Is there some reason why Samantha wears the same exact "Heart Pendant Necklace" in every single episode? It seems odd that she only has one necklace all the time.
Question: In one episode (not sure which one but it was in the Dick York era), Darrin was arguing with Samantha and said something like "Confiding in a woman is like broadcasting by Telstar." What exactly does that mean and what was Telstar?
Answer: The Telstar Reference was in Dangerous Diaper Dan when Samantha engages in too much gossip.
Answer: The original diamond and white gold heart necklace was given to Elizabeth Montgomery by her then real-life husband, William Asher, who also directed the show. She wore it in nearly every early episode. When the necklace was lost or stolen about mid-way through the series, Montgomery had two replicas made from rhinestones. She wore either one of those for the rest of the show's run.
