It's Always Sunny in Philadelphia - Season 3 (2007)

The McPoyle brothers and sister Margaret take the gang hostage at Paddy's, raising the stakes to a new level in the feud between the two groups.

Dee discovers that the biggest loser and fatty from high school is now a successful and thin fashion designer... now making Dee the biggest loser.

As they prepare for the annual Pub Crawl, the gang is horrified to learn that they face competition from a new Korean bar.

A corporate chain offers to buy the Paddy's Pub, leaving Dee and Charlie unemployed and forcing them to find jobs at another restaurant, where they abuse their positions and take advantage of the manager, who is Dee's friend.

In their quest to become famous, Frank, Charlie, and Mac, search for newsworthy footage to air on public access.

While Dennis and Dee try to figure out if the rapper Dee is dating has a mental handicap or not, Charlie, Mac, and Frank try to start their own band without knowledge of how to play musical instruments.

After reading that a serial killer is on the loose, the gang notices that Mac is acting shady and decides to find out if he's the man behind the murders.

Dennis is angry because he's being mistaken for a fat guy rather than the sex offender who moved next door to Charlie. Meanwhile, Mac's father is released from prison and he and Mac have some catching up to do.

After stumbling upon a kilo of cocaine, the gang is forced to pay off a $25,000 debt to the mob. Mac becomes a mob informant, while Frank pimps out Dennis as an escort at the local country club. Charlie stumbles upon an opportunity to sell illegal narcotics.

While paying off their debt to the mob, Charlie and Dee try to find a way to make fake cocaine in order to fool them, while Dennis ranks in thousands of dollars being pimped out at the local country club. Mac realizes his position as a mob informant isn't being utilized to its full potential.

Dee and Mac become Guardian Angels and clean up the streets when a bum starts using the alley behind the bar to masturbate. Meanwhile, Dennis, Charlie, and Frank impersonate police officers in order to get preferential treatment.

After Charlie accidentally puts Paddy's Pub up for 1st prize in a local dance competition, Frank makes the gang participate in the contest. Here, they form alliances and try to cheat the other contestants, as well as themselves, out of first place.
