Rule #1: NEVER mess with the man with the mic in his hand. Wu-Tang rapper Ghostface Killah was performing at a tattoo convention in Amarillo, Texas last week when a mouthy fan started giving him the finger and cursing at him for no apparent reason. Ghostface threatened the man from the stage area, letting him know he needs to CHILL asap before he gets punched in the face. However, GK’s super loyal fans ended up jumping the dude with the attitude problem, teaching him a serious lesson. The cops dragged the man out and police questioned him, but no charges were filed. But of course just as we’d expect, the whole ordeal was caught on tape. Check out the video below!
