The Internet exists for exactly this reason: In a four-year old post for Baseball Prospectus, Larry Granillo looked closely to determine exactly what Cubs game Ferris Bueller and his friends attended in the 1986 classic Ferris Bueller’s Day Off. And based on what little information about the game we get from the
movie — mostly the scene where Ed Rooney watches a portion of the
broadcast inside a pizza place — Granillo determined that the game that provided the setting happened on June 5, 1985, exactly 30 years ago
Friday. This is the 30th anniversary of Ferris Bueller’s day off.
