Pete's making a TV advert and the advert producers want to film it in the Rokeby's front room. Yetta, dubbing herself Yetta Garbo, is thrilled at the chance of stardom. Pete of course doesn't want her anywhere near the cameras but her influence is unstoppable.
David is cast as the lead character of the commercial and manages to blackmail his sister into being his chaperon, but Tammy's a bit more preoccupied with one of the production assistants to really care.
Meanwhile Yetta's twice removed cousin Dolly turns up. Past hatred between the two is revealed which spells bad news for Pete when Dolly herself also gets cast in the advert.
