This week's question was just how is former Friends (and Misfits of Science; let's not forget) star Courtney Cox related to late original Hollywood Squares regular Charlie Weaver.
The answer is that Charlie Weaver was a character created by actor Cliff Arquette, who was the grandfather of David Arquette, Courtney Cox's hunsband. Thus Weaver/Arquette is Courtney Cox's Grandfather-in-law.
