Cory is invited to a pary, but Shawn isn't. Cory thinks that he is cool. Alan thinks he is old when he gets catalogs for old people and he throws out his back. Amy makes him get up after he decides to lie on the couch all day. The reason Cory was invited was because Melissa, the host, had to uninvite all the real cool guys and invite geeks instead.
This was a good episode! I liked how Shawn wasn't all prideful and looked down on Cory. He told him that they would always be friends no matter how cool they are. I give this episode a 9.5!
