Exclusive: Howie Mandel's VIP 'America's Got Talent' Backstage Tour

Ever wonder just how they put together "America's Got Talent"? No one has been allowed behind the scenes until now, and our own Samantha Harris is exclusively backstage with judge Howie Mandel to reveal the magic!

Of course, Howie is no ordinary tour guide, and keeping up with the funnyman requires fleet feet as he makes fun of the crew and plays practical jokes on fellow judge Piers Morgan.

"America's Got Talent" is one of the summer's biggest hits, with crazy acts vying for the million-dollar prize. Howie judges alongside Piers and Sharon Osbourne, with Nick Cannon hosting. The show airs Tuesday and Wednesday nights on NBC.
