Howard Stern Signs on with America's Got Talent!!  Replacing Piers Morgan!  Can I just tell you how exciting this is???  I didn't really watch the show before, but I will this season.  OK, maybe I'm playing favorites here because I'm a radio geek, but you have to admit that Howard understands the audience, as well as talent when he sees it.  All the more reason why this guy is the PERFECT judge!
