It's Always Sunny in Philadelphia (2005)

Chardee MacDennis: The Game of Games (season 7, 2011) With no scheme to chase, the gang stays in Paddy's Pub and plays the drinking game they invented, part trivia contest and part drunken dare, with three levels: mind, body and spirit. Keeping all five together in one room strips away the plot machinery the show usually relies on and leaves only what makes it funny, which is how badly these people treat each other when they are bored. The invented rules give the episode its own escalating structure, so it never feels like filler. Watch it once you know the characters, since most of the laughs come from seeing their worst habits weaponized.
