We don't know how, or why, or when it happened, but at some point, exposing spoilers became the most atrocious breach of social decorum known to man. (Somehow, we're sure "The Phantom Menace" is to blame.)
In this clip from the upcoming season of "Portlandia," premiering this Friday on IFC, Fred and Carrie throw a dinner party that quickly devolves into two couples debating about which TV shows and movies can possibly be talked about without offending someone who has yet to watch them.
Oh, and be sure to watch to the end for a twist ending. But we don't want to spoil anything.
