Fans of Seinfeld and Arrested Development might be interested in It’s Always Sunny in Philadelphia, a comedy about a band of hapless, self-interested pub owners in which slapstick hijinks obscure the fact that nothing much ever happens (for example: a wheelchair race/brawl in a mall between two characters pretending to be handicapped to get girls). The first episode of the fifth season premiers this Friday but you can watch past episodes free at FX.
