20 Things You Didn't Know About High Fidelity

10. Rob's Black Book Is A Reference To John Cusack's High School

Viewers might remember that Rob has a small black notebook containing the phone numbers of all his ex-girlfriends, which is adorned with musical stickers that vaguely conceal that the book is actually a Chandler's assignment notebook.

This is notable because the notebook was a required item for every student at Evanston Township High School, which Cusack himself attended as a youngster and graduated from in 1984.

While there's no confirmation that the notebook is the very same one Cusack himself used as a student, it's still a cute little shoutout to an institution which defined his formative years.
