The Paddy's Pub Gang is gearing up for their triumphant Season 7 return on September 15th, and in anticipation of this gloriously debauched new run of episodes, FX has released two It's Always Sunny in Philadelphia Behind-the-Scenes Featurettes.

Just don't cough any blood on them or kill a hooker in the process.
