'It's Always Sunny In Philadelphia' Season 6 Blooper Reel Is Amazing (VIDEO)

It seems like only yesterday that "It's Always Sunny In Philadelphia" featured skinny Mac and non-movie star Charlie Day in its stellar cast. Although "It's Always Sunny" got perhaps its most attention than ever right before season 7, which airs its second episode tonight, devotees know that the FX comedy has been consistently solid television since the beginning.

Which is why we're glad that their official YouTube channel has released the season 6 blooper reel, aptly titled "The Gang F*cks Up." (It's officially sanctioned, too, so it won't be pulled offline like the awesome "Parks and Recreation" blooper reels!)

Watch as Danny DeVito, Charlie Day, Glenn Howerton, Rob McElhenny, Caitlin Olsen and the rest of the supporting cast barely keep it together while shooting plots that get increasingly ludicrous. Our personal favorite: The cast cracking up over graphic descriptions of Sir Ian McKellan's sex life.
