Our friend, Riff Raff, was recently performing at Ohio State when some idiot threw a beer can at him while on stage. Needless to say, the rapper/entertainer was not too pleased with the behavior of this "knucklehead" and he him know it.

We should Warn You, some of you may find the language in this video to be disturbing, but watch as Riff Raff stops his performance and invites the person who threw the can to come on stage. The rapper issued an open challenge after just performing two songs and then walked off stage.

Having met this guy, I must admit he is one of the nicest guys you will ever meet and for someone to do this during his performance is just immature. I'd love to have seen the person who threw the can take Riff Raff's challenge because we know one thing, Riff Raff is in really good shape and could have probably taken matters into his own hands.
