In this episode Cory and Shawn fight when Cory applies to Stanford, because Shawn knows with his grades he could never get in there. So Cory replaces Shawn, and Shawn replaces Cory with new best friends. At the end of the episode we are treated to a flashback in which we are revealed to see how Cory and Shawn became friends. One saved the other at a zoo. They hug and of course everything is back to normal.
A good episode, pretty funny, a good plot and showed us how they became such good friends. Overall grade is an A
