We're used to seeing weirdos and no-talents perform on America's Got Talent, but the following will warm your heart and bring a tear to your eye. Nine-year-old David here was diagnosed with autism and didn't speak until he was three. The guy who drove his bus to school, though, told his mom he would sing all the way to school and all the way back. What a treat! He's got a lovely little voice reminiscent of Michael Jackson's as a kid. And here he is singing "Ben." (Sniffle, sniffle.)
