It's Always Sunny in Philadelphia

The gang discovers the perks of being handicapped when Charlie becomes wheelchair-bound after getting hit by Dennis' car.  Meanwhile, Dennis and Dee's estranged father, Frank Reynolds, returns to town to reconnect with his kids, who want nothing to do with their father.  Frank has a blast hanging with the gang and decides to settle in South Philly permanently, and becomes Charlie's roomie.

The gang discovers they may lose part of their bar due to a zoning mishap and an overzealous new business neighbor, and use unorthodox measures to remedy the situation.  Meanwhile, Dennis and Dee's mother, Barbara, returns to town and makes Frank's life miserable, and Frank takes steps to cement his roots in South Philly when he becomes part owner of Paddy's.

Realizing they can no longer stand to work with their father, Dennis and Dee quit their jobs at Paddy's and they concoct a plan to get welfare benefits so they can pursue their real, and completely unrealistic, dreams and goals. Mac and Charlie soon experience the downside of Dennis and Dee's absence when Frank starts dumping all the work on them, and, even worse, tries to be a father figure to them.

Jealous of Frank's newfound happiness reconnecting with his kids and reliving his youth, Barbara gets back at Frank by having sex with Mac. This one act sets in motion a series of back-stabbing and deceptive moves among our gang as they use the threat of sex for their own selfish purposes.

After getting mugged, Dee agrees to take boxing lessons from Frank, who's thrilled with the prospect of reliving his glory days as a pro-fighter. Frank encounters his former nemesis at the old gym and gets the chance to rewrite their history. Meanwhile, Mac and Dennis hope to make some cash by entering Charlie in an underground street fight match, and Dee and Charlie dabble with performance enhancing supplements.

After being arrested for arson the gang is sentenced to do community service. Frank makes an effort to connect more with Dennis. Meanwhile, Charlie is also ordered to attend AA where he makes a startling discovery that might be beneficial in his ongoing quest to hook up with the Waitress.

When a leaky pipe creates a water stain on the wall at Paddy's that resembles the likeness of the Virgin Mary, the gang argues over the best way to exploit their little "miracle."

The gang explores the corrupt world of local Philly politics when Frank explains how easy it is to elicit bribes from politicians.  However, the gang's initial pursuit of a quick cash pay-off soon falls to the wayside when Dennis begins to think seriously about running for office.

While the gang debates the constitutionality of various bans on people's rights, Mac and Dennis decide to turn Paddy's into a freedom zone with no restrictions or rules, and quickly discover the disadvantages of having too much freedom. Meanwhile, Frank gets a kick out of the whole freedom situation and decides to have a little fun of his own.

Dee is concerned when she receives numerous emails on her myspace.com page from a stranger claiming to be her and Dennis' father, and she arranges a family dinner with Frank and Barbara to get to the truth. Meanwhile, all this father-talk strikes a sentimental chord in Mac and inspires him to reconnect with his father who is in prison.
