Mandel, now the longest-standing judge, with 15 seasons under his belt, calls the show “the epicenter of hope and dreams coming true.” After seeing that confetti rain down on winners, it’s hard to disagree. “There are moments that really stick out,” Mandel says. “When they do, you know that you’ve been witness to something incredibly special.”

America’s Got Talent celebrates 20 seasons with a special trailer. The show returns on May 27 at 8 p.m. ET on NBC. The new season features past winners, returning contestants and Mel B’s return as a judge.
