Notorious shock jock Howard Stern made an energetic debut on the season-seven premiere of NBC\'s \"America\'s Got Talent\" on May 14. The newest addition to the judges\' panel was heralded by a slew of cheering fans, and at one point Stern even gamely got on stage to bust a move.

The clip has racked up millions of views online. Check out the entire episode and then let us know what you think of Stern as an AGT judge.
