While the episode itself wasn't quite in the top 10, I think this represents a recommitment to the morbid nihilist humor that made the show so popular in the first place. The series never really shied away from shock humor, but season 5 showed that shock alone doesn't make great entertainment. Season 5 was all shock, no humor. Season 6 was all humor, no shock.
It really is a ray of hope to see this show has found a way to make the macabre and absurd feel smart again, even if the episode didn't have any moral to the story. I had a lot of fun watching this one. It definitely seems adult swim was leading with it's weak episodes this season.
