Question: I'm going crazy! I've been watching reruns of The Cosby Show from the '80s. In so many of the episodes, Bill Cosby wears a black-and-white pin that looks like it has an s and p on it. Will you please tell me what significance this pin had and what it represented? — Janet T., Martinsville, Ind.
Televisionary: Actually, the pin had the initials "S.D." on it, along with a small "Jr." Cosby wore it in memory of Sammy Davis Jr., who died in 1990.
