A year ago, before there was a Cleveland Show, when the Family Guy spinoff was still just a possibility, the show's first guest stars, Daryl Hall and John Oates, were brought aboard. They'll finally make their debut, playing an angel and a devil, respectively, on Cleveland Brown's shoulder on the Thanksgiving episode which airs Sunday at 8:30PM on Fox.

According to show co-creator, producer, and voice of Cleveland Mike Henry, the appearance came out of a trip to Las Vegas where a casting director arranged for Henry to meet the guys backstage after a show. When they showed interest, that was that. "We wrote the part and sent it on over," says Henry, speaking at a conference call with media.

"You planted the seed a year ago saying, hey, would you like to be on the show that's not on TV yet?" says Hall.

Whatever big decision Cleveland is making in the episode, Henry is a bit cagey. "Maybe Auntie Mamma has got a penis," says Henry. "Let's just say that. There. I've given it away."
