Mark McGrath Goes Off on Fan [VIDEO]

In where are they now news, where the hell has Mark McGrath been? Apparently missing his anger management classes. A video has surfaced online, of the Sugar Ray frontman, going ballistic on a fan for muttering the words "Sugar Gay." Watch as Mark destroys a fan for his choice of words. Also, be warned that Mark doesn't have a very large vocabulary when he is angry, so the video is obviously NSFW.
