Australia comedian Alex "Shooter:" Williamson had a glass thrown at him on stage after he launched into a vile tirade at a heckler who was talking during his set.
The 32-year-old was performing in Adelaide on the weekend when his attention was caught by a man "talking about his Jameson" instead of listening to his gig.
Williamson suddenly turned on the audience member, becoming violent and delivering a vicious personal spray.
"You were raised like a c***. I am glad [your parents] are f***ing dead so they didn't have to see their son evolve into such a f***ing useless sack of sh*t," Williamson yelled into the microphone to the audience member.
The heckler then responded to Williamson's rant, saying he hadn't laughed once during the set.
