Always sunny Season 5 DVD Box Set

Storyline

Four egocentric friends who run a neighborhood Irish pub in Philadelphia try to find their way through the adult world of work and relationships. Unfortunately, their warped views and precarious judgments often lead them to trouble, creating a myriad of uncomfortable situations that usually only get worse before they get better.

There are so few television comedies that generate as much humor with generally unlikable characters, and "Sunny" probably tops the list. "Strangers With Candy" and "Absolutely Fabulous" come closest to capturing the laugh-out loud comedy it generates. Part abstract theatre, part absurdist drama, "Sunny" not only skewers every hot-button issue imaginable, but barbecues and presents it as a scrumptuous entree. And the zingers ... "Which one of you fags is my dad?" and "You might as well call it Rape Bar" are killer. Plus being a Philly boy myself, the opening montage with images of The Linc and 30th Street Station are always good for a smile. With "Drawn Together" set for its impending exit, "It's Always Sunny in Philadelphia" is the reigning TV king of comedy.
