Jack Black almost causes 'fatal accident' for Jennifer Aniston on 'The Gong Show'

Jack Black was a gonging machine while participating as a guest judge on The Gong Show. But Black had trouble controlling his tenacious mallet-swinging, and it wasn’t long before he gave himself a possible concussion.

While gonging a contestant, Black swung the mallet so hard that it bounced off the gong and right back into the actor’s head. The dazed Black said, “I gonged that thing so hard, it bounced off, like, my temple and I don’t remember … like, the last 45 seconds. But I remember it was really bad!”

Despite the head injury, Black kept gonging contestants. He gonged so many that occasionally the other judges would try to physically stop him.

Jennifer Aniston attempted to block Black on one such occasion, but the actor managed to throw the mallet into the gong anyway. But her threw it so hard that it bounced back viciously and almost clobbered Aniston.

A shocked Black said, “That almost ended tragically. … It almost took her head off.”

Unharmed, Aniston joked, “My life just almost ended.”

Realizing that he had narrowly avoided seriously injuring himself or Aniston, Black said jokingly, “Once again, there was almost a fatal accident with the bouncing gong. Thank God that didn’t go the way it seemed like it was gonna go.”

The Gong Show airs Thursdays at 10 p.m. on ABC. Watch clips and full episodes of The Gong Show free on Yahoo View.
