Family Guy (1999) - 2x09 - If I'm Dyin' I'm Lyin'

When Peter's favorite show, Gumbel 2 Gumbel, faces cancellation, he takes drastic measures to save it. Using Chris as bait for "The Make-A-Dream-Come-True" Foundation, Peter tells them that Chris' dying wish is that the show be renewed. But when the Foundation arrives to check up on Chris' "tumorsyphillis-itis-osis", Peter panics and tells them that Chris was miraculously cured. Word spreads of the "miracle" and Peter becomes the "Miracle Healer of Quahog." Of course, Peter loves the attention and Lois thinks it's immoral to live such a lie. When the Griffins become mysteriously plagued by everything from locusts to bloody bathwater, Lois forces Peter to end the charade.
