At a recent NOFX show in Sydney, Australia, a fan decided to climb onstage and put his arm around Fat Mike. In the video below, Fat Mike then proceedes to absolutely kick the living shit out of him—hitting him in the face and kicking him in the head—before security escorts the stunned fan offstage.

Moral of the story: Don’t touch Fat Mike. Check out video of the incident below, and let us know your thoughts.

Fat Mike eventually made up with the fan—who showed off his busted lip—on Twitter.
