In a simiar vein (no pun intended), Suzanne Somers used to do the "Chrissy" character from Three's Company in her Las Vegas routine until the producers of the sitcom took legal action against her. It led to all sorts of squabbling over who truly created the character, and brings up an interesting point. How much of a television (or film) character is created by the writer(s) and how much is a creation of the actor portraying the character?
