FX's original comedy series It's Always Sunny in Philadelphia is back for a 6th season, and that can only mean more antics from everyone's favorite bar owners!

Step into Paddy's Pub with Mac (Rob McElhenney), Dennis (Glenn Howerton), Charlie (Charlie Day), Dee (Kaitlin Olson), and Frank (Danny DeVito) – all friends working in harmony for a common cause: themselves.

Last season saw the gang dabble in failed interventions, the poisoning of frat kids, footwear for kittens, dick towels, and an uncensored Christmas special with a gruesomely-violent claymation sequence.

This year the stakes are higher, and so is the definition as we've made the switch to HD! Watch them tackle gay marriage, fight the class war, battle the high seas on a houseboat, bash rats, get repulsed by the McPoyles, deal with a very mysterious pregnancy and much more that you'll simply have to tune in to see.

So come September check your conscience at the door and tell the kids to go play outside because it's about to get sunny in Philadelphia all over again.

It's Always Sunny in Philadelphia was created by McElhenney and is executive produced by McElhenney, Day, Howerton, Michael Rotenberg, Nick Frenkel and Tom Lofaro. The show is produced by FX Productions.
