Offstage, Sal Valentinetti is a 20-year-old pizza delivery guy from Long Island, New York. Onstage, he's the reincarnation of Frank Sinatra. His old-school persona is a throwback to the time when the Rat Pack ruled Las Vegas.

"I'm gonna entertain yous like you've never been entertained before," he told the America's Got Talent judges, sounding like he just stepped out of a Scorsese movie. "As a matter fact, I didn't come here to try out. I came here to win."

He then launched into a performance of the Sinatra standard "My Way," which had the auditorium on its feet by the end. His mother in the crowd was in tears. He earned raves from the judges, even Simon Cowell, who called him an "old soul" and said his late grandmother, who introduced him to this music, is looking down on him with pride. And Heidi Klum hit her golden buzzer, automatically sending Valentinetti through to the live rounds.

You gotta see this guy.
