The all new cast of 'It's Always Sunny In Philadelphia' consists of Haley Joel Osment (yes, the 'I see dead people' kid), Xzibit, UFC star Chael Sonnen, Candace Cameron, and Andrew Dice Clay! Of course, this is a gag promo, as the real cast will still be on the show...or maybe these characters will have something to do with the new season? I guess we'll have to wait and find out when the show airs the start of it's new season October 11th. Check out the hilarious promo!
