Joan Rivers – Celebrity Cameos on ‘The Simpsons’
Okay, so she's more of a mouthy broad than she is an actress, but comedian Joan Rivers appeared in 'Viva Ned Flanders' during the 10th season of 'The Simpsons.'
In the episode, Ned and Homer travel to Las Vegas after they learn that Mr. Burns' casino is about to be demolished. And among the adventure's many shenanigans is a scene with Rivers popping up out of nowhere asking Ned to be in an infomercial.
While her appearance runs just shy of 20 seconds, Warren Martyn and Adrian Wood, authors of the book 'I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide,' praised her scene and called it "hysterical."
