This one was much better than the previous one and although it had some weak moments, it's one of the best since season 11.
The joke itself wasn't that great, but it was hilarious to see how freaked out Butters was and how Cartman was manipulating everything so he could have his way.
The guy who acted like it was his joke wasn't that funny, but maybe because I'm not from America and I don't know anything about him, so...
Cartman's alternate realities were the best, especially with the Jewbots and The Human Torch impression.
Kanye West was a bit over the top, but his House-way of thinking and the song parody were hilarious.
