Not put down by this, Cory and Shawn walk the halls of John Adams High and bump into a teacher, who they mistake as for Harley. It is then clarified that the teacher they met is a new teacher— Jonathan Turner, who immediately earns a reputation for being a cool teacher, and described by Cory and Shawn as "Feeny with an earring." After class, Cory crosses paths with the real Harley Keiner and after making small talk, immediately gets threatened. Harley lets Cory off the hook, but catches the attention of another teacher, who sends Harley and Cory ("Johnny Baboon") to the principal's office. Feeling like his high school experience couldn't get worse, Cory is shocked to find out that Mr. Feeny has been promoted to high school principal.
