it's always sunny in philadelphia

Starting Thursday, September 15th, the gang of ‘It’s Always Sunny in Philadelphia’ is back and this season, the cast brags that they’re filthier than ever. To get a taste of what’s to come (We’ll give you a hint: it involves a ton of balls), check out the  season seven trailer below (some NSFW language ahead):

When the cast of ‘It’s Always Sunny in Philadelphia’ cast showed up at Comic-Con dressed as the characters from the show’s epic, ridiculous rock opera episode “The Nightman Cometh,” it was pretty inevitable that they would end up doing a musical number. So here they are, pleasing the crowd with a sing-a-long rendition of ‘Day Man,’ from that episode.
