This is overkill. This one episode is probably one of the most hilarious anime episodes I've watched so far. It's like a one really big point to whole Lucky Star series. There are jokes about: Azumanga Daioh, Bakemonogatari, of course Haruhi, Hatsune Miku, and many more. I was laughing my ass off for quite a while watching it. This is why I gave it 10/10, better score than Lucky Star itself.
