Crude, controversial, outlandish, and downright hilarious. The gang's all back for a 5th season of FX's original comedy series It's Always Sunny in Philadelphia. Come join Charlie (Charlie Day), Mac (Rob McElhenney), Dennis (Glenn Howerton), Sweet Dee (Kaitlin Olson), and Frank (Danny DeVito), the self-centered owners of Paddy's Pub in Philadelphia who will do just about anything, no matter how reprehensible, in an attempt to better their own situation. Coming off a season in which they performed a musical, pooped the bed, and nearly died, you would think the gang would have learned their lesson by now. Well, think again.
