It takes a lot to shock the America's Got Talent judges, but that's just what 82-year-old John Hetlinger did. The retired aerospace engineer (he helped repair the Hubble Space Telescope!) started doing karaoke about 15 years ago when he retired.
"This would probably be a high point of my life and many careers," Hetlinger told Simon Cowell when the judge asked why he's on America's Got Talent today. And then Hetlinger started rocking out.
Yes, the 82-year-old man started singing "Bodies," a heavy metal song by Drowning Pools. His performance got a standing ovation from the audience and judge Howie Mandel.
