This episode is a top 5 all time, right up there with Rabbit Ears. This is what American Dad! Does best. When the writers are allowed to really run with these bizarre ideas it always pays off. Also, over the last few seasons they've really managed to make me care about this family that's made up of terrible people. The humor has also evolved away from pop culture references into absurdism and jokes that rely on the characters or the world they've built. They've been consistently pulling the rug out from under my expectations this entire season. If you're a true fan and like the weird episodes, this will be one of your favorites for sure.
