Killer Mike and El-P had to fight off an apparently deranged man after he stormed the stage during their Monday evening set at South by Southwest and attempted to get physical with the Run the Jewels emcees. Fortunately, Mike Bigga saw the attack coming and quickly shoved the man offstage where things got quite a bit more violent once the rap duo's crew joined the brawl.
Once back onstage, Killer Mike led the crowd in a chant of "f**k boy" before continuing the show.
