Olive (Rudge) Butler (Anna Karen) is one of the main characters of the television series. She is Stan's sister. In all but the last series and a few individual episodes in other series, Olive hangs around the home all day in her dressing gown, until she divorces Arthur in the last season of the show and gets a job as a conductor ('clippie') on the buses.

She is married to Arthur Rudge until the final season of the show. Arthur constantly insults her as well as the other members of her family especially Stan Butler, and his best friend Jack Harper who make nasty jibes at Olive Rudge as well as when and before she became a clippie she is always the butt of everyone's jokes.
