He’s always up for a great time, and Will Ferrell revisited his college glory days on Monday evening (October 14).

The “Old School” star donned the Tommy Trojan mascot attire and served as a drum major for the University of Southern California marching band.

Ferrell was hilarious as he screwed up pretty much every move while proudly flaunting his plumed hat and metal chest plate.

The whole event was a rally for Will’s friend Craig Pollard’s charity Cancer for College, which raises money to offer scholarships to cancer patients so they can attend classes.
