One brief line from Shakespeare makes its way into the mouth of a character played by Sammy Davis, Jr. in a fifth-season episode of The Cosby Show.
The plot involves a character who has never learned to read or write. At the end of the episode, he chances upon a retired English teacher—played by the astonishing Arnold Stang (you'll recognize his voice instantly)—who offers to teach him. Observe:
The quote Arnold Stang’s character gives in reply—“Oh, gods and worms, what mockery!”—isn't from Shakespeare at all. It comes from Winterset by Maxwell Anderson, about which I know nothing.
