I read an interview yesterday where Hader compared the latest episode to the Sopranos "Pine Barrens" episode. The one where Paulie and Christopher are trying to kill this Russian mobster out in the woods in the middle of winter. The guy just won't die. (In the end I think he gets away.) The whole episode is this surreal set-piece, kind of an out-of-context one-off. Just this weird interlude in the overall plot arc.
