Obviously the conceit of this gag is meant to be absurd — you can’t have It’s Always Sunny in Philadelphia without the original cast, right? Right guys? But I’m not so sure this promo video featuring an all new replacement cast for the FX comedy — with Haley Joel Osment as Mac, Candace Cameron as Charlie, Andrew Dice Clay as Frank, Xzibit as Dee, and UFC broski Chael Sonnen as Dennis — is such a good idea. This is the most I’ve laughed at anything to do with the once-brilliant, now-spinning-its-wheels show in a long time. It feels like introducing your girlfriend to your funnier, better looking best friend who she hasn’t had to deal with yelling about nothing and getting drunk all day for the past couple years. It’s just going to be hard to look like a more appealing option after that.
