It's Always Sunny in Philadelphia: Season 4

Step up to the bar at Paddy's Pub and brace yourself for a shot of outrageous fun! Paddy's may be the worst bar in Philadelphia, but the gang there sure knows how to party. Whether it's Dee and Charlie's flirtation with cannibalism, Frank's glory-hole fixation, or Mac's raucous reenactment of Dennis's over-the-top sexual memoirs, nothing is sacred for these dysfunctional misfits as they hilariously destroy all possible boundaries of good taste. This set includes every episode of Season 4, including the hilarious musical finale: "The Nightman Cometh."
