Full Metal Geriatric: 82-Year-Old Man Surprises 'America's Got Talent' With Hard Rock Tune

It wasn't just the bodies but the jaws that hit the floor.

A Colorado man is out to prove that you're never too old to rock out.

When 82-year-old John Hetlinger — donning high-waisted khakis and a button-down shirt with a cartoon toucan  strutted to the America’s Got Talent stage Tuesday night, the sound out of his mouth was the last thing anyone, judges included, expected.

Hetlinger has lived a storied life. He flew jets in the Navy, helped fix the Hubble Telescope for NASA, but he said being on AGT was the highlight of his life.

Now retired for 15 years, Hetlinger says he loves karaoke and performed his favorite tune to sing, Drowning Pool’s 2001 hit, “Bodies.”

In an unsuspecting performance, the crowd stood up, headbanging to the heavy metal tune, throwing fists in the air in front of the stunned judges.

Mel B. and Heidi Klum looked as if they had seen a ghost; Simon Cowell could not hide his laughter and surprise, while Howie Mandel sported an ear-to-ear smile.

Host Nick Cannon had a look of shock on his face, and could not figure out what to make of the performance.

Hetlinger made such an impact with the judges that he went through to the next round. 

And it wasn't Hetlinger's first heavy metal rodeo, as he has performed the song before. He has shared a video of a 2014 performance of the tune on his Facebook page.
