"It's Always Sunny In Philadelphia" Season 6, Episode 1: The Gang Is Back

NEW YORK (CBS) The gang was all back at Paddy's Pub Thursday night, when season six of the series "It's Always Sunny In Philadelphia" began .

The FX series follows The Gang, a group of five underachievers who run Paddy's Pub in South Philadelphia. It stars Glenn Howerton, Kaitlin Olson, Rob McElhenney, Charlie Day and Danny DeVito at "the most freedom loving bar in America."

The gang is never afraid to tackle salient issues including abortion, homelessness, gay marriage or the sexual adventures of the character Mac.

This season,Mac is upset by the fact that his post-op transsexual ex-girlfriend is now "gay married" to someone who isn't him; Dennis is upset that he's not yet married to anyone; and Charlie and Frank have decided that the best resolution to Charlie's lack of health insurance was to get gay married to each other. Also, Dee pretty much just wants to have sex with whomever will take her, since Mac told her he'd rather "get shot in the face" than marry her.
