It's Always Sunny in Philadelphia

Never have more despicable characters been more likeable than on the FX comedy It's Always Sunny in Philadelphia. The low-budget show—about a group of conspiring, selfish friends all arguably with borderline (or, in some cases, full-fledged) personality disorders—is mercilessly funny. Developed in 2005 by then out-of-work actors Rob McElhenney and Glenn Howerton, the series cracks jokes that venture into territories of clever offensiveness and twisted whimsy usually reserved for animated shows such as South Park or Family Guy. Sunny revolves around narcissistic twins Dennis (Howerton) and Dee Reynolds (Kaitlin Olson), who run a bar in Philly along with their friends, the delusional Mac (McElhenney) and none-too-bright Charlie (Charlie Day). Adding Danny DeVito to the cast as Dennis and Dee's adoptive father, Frank, after the first season to give it some star power, the show has a following that has grown exponentially since its nascent days, anchoring FX's bold and well-received comedy lineup. Sunny makes the sacred profane, and the profane sacred—creating a challenge for the writers and actors to draw humor from some of the darkest and unlikeliest places. There's a reason dirty comedy is often frowned upon—it's rarely done well—but the Gang (as they're known) should be embraced with open drunken arms.
