Most Americans know Run-D.M.C. thanks to a brainstorm by producer Rick Rubin. Instead of just borrowing Aerosmith's guitar lick from "Walk This Way," he got the idea to incorporate the original band in the song and the video. But there's much more to this legendary hip-hop trio, as you'll learn in this quiz. Congratulations to Run-D.M.C. for their enshrinement alongside other musical legends in the Rock & Roll Hall of Fame!
