'It's Always Sunny In Philadelphia' Gets New Cast In Spoof Trailer Featuring Haley Joel Osment, Xzibit, Candace Cameron, Andrew Dice Clay (VIDEO)

"It's Always Sunny In Philadelphia" has released a new spoof trailer for its upcoming eighth season that introduces a completely new cast. The raunchy gang TV viewers have come to know and love have been replaced by a motley crew of washed-up celebrities that includes Haley Joel Osment, Xzibit, former "Full House" star Candace Cameron, Andrew Dice Clay and UFC fighter Chael Sonnen.

In this mockumentary-style video, the original cast claims they left the show because they wanted to spend more time with their families, but FX President John Landgraf offers a different explanation: "They were fired. We brought in a new cast and tested it with audiences, and they liked it even better."

The clip features all sorts of "Sunny" hilarity, like Haley Joel Osment wondering if Rob McElhenney died, Xzibit playing Sweet Dee and an all-grown up D.J. Tanner exclaiming, "Kitten mittens!" It also reveals that sadly, Fat Mac is no more.

"It's Always Sunny In Philadelphia" premieres Thurs., Oct. 11 at 10 p.m. ET on FX.
