Peggy wants to help the cheerleaders do real cheers. She gets a job as the new cheerleader coach. She starts using lots of violence in her cheers. She then makes fun of the Irish in one of her cheer though which causes a big deal.
This is a good episode because it is very funny. Although it is a very Peggy heavy episode and for those, like me, who hate Peggy this takes away from the episode. If you do like Peggy however you should really enjoy this episode because at the end she comes out on top kind of.
