We use Google so you don’t have to. Every so often I wonder about things, and I figured that other people might wonder as well. So, every so often I’ll post answers to things that I wonder about, just in case you were wondering too.
Today’s question: What is the “SD” button that Bill Cosby wears in “The Cosby Show?”
Bill Cosby wore the button in the later seasons of the show. It says “SD Jr” in honor of his friend Sammy Davis Jr., who died in 1990.
