During yesterday's Fourth of July Jam in Philadelphia, DJ Jazzy Jeff (sans Fresh Prince) and Jeremy Ellis got into a Super Mario Bros. remix battle, accompanied by The Roots. This is a thing that happened.
Philly's Action News 6 (via Nintendo Life) posted footage of the epic DJ battle, which DJ Jazzy Jeff won solely based on the fact that he's DJ Jazzy Jeff and I had to Google Jeremy Ellis. He seems like a lovely man, but he knew who he was up against.
