(CBS/AP) NEW YORK - When "America's Got Talent" returns tonight, Howard Stern will be on the judging panel, and the shock jock says his critics should watch the show before attacking him.
Stern debuts as Piers Morgan's replacement on NBC's summertime talent show, but a group that calls attention to bad language and risque content on television has already objected to his presence on the show.
The Parents Television Council said the radio shock jock's addition "will likely result in a sharp increase in explicit content," and has asked advertisers to stay away.
Stern dismissed those concerns during an appearance last week on "The View."
"First of all, I think it's kind of silly of anyone to say, 'Gee, we're against Howard on the show,' and they haven't seen the show," he said, according to the Hollywood Reporter. "What I would suggest is that they would really tune in Monday night, see what I do. What I'm gonna do is be a very serious judge."
In an hour-long, expletive-free news conference on Thursday, Stern said he fully understands that "AGT" is a family-friendly show.
"I really feel a responsibility to the people who love this show already," he said. "In no way, do I want to get in the way of it. I want to broaden it and make it better."
NBC moved the show's base from California to Newark, N.J., to accommodate Stern's satellite radio schedule when he agreed to replace Morgan. He said he has taken the role of being the "honest" judge who doesn't sugarcoat things for contestants.
Stern said he was a fan of the show before being asked to be on it, preferring it to "American Idol" because the wider variety of acts on "America's Got Talent" makes it seem like vaudeville.
"I didn't need the money," he said. "I didn't need more fame. I certainly feel famous enough. I'm comfortable in my life. I just love the show and thought how much fun it would be to do it."
He's paired with Howie Mandel and Sharon Osbourne as judges, and offered praise for their work. He flashed attitude about some rivals, though: "American Idol" makes him want to throw up, he said, and host Ryan Seacrest is "tired."
"J.Lo, I don't even know what she's doing there," he said of "Idol" judge Jennifer Lopez. Of Britney Spears, who hasas a new judge on "The X Factor," he said people are going to tune in to see "if she can function through the whole thing."
"I think Britney is going to stand there and eat a lollipop and wear a sexy outfit and I don't expect great opinions out of her," he added. "I'll tune in and see what kind of a train wreck she is."
Stern said he thinks his radio audience is ready to see him try something new. He's curious about how it turns out; his usual experience is turning around a low-performing asset, but in "America's Got Talent," he's joining a show that already has a successful track record.
"If it doesn't work, I'll crawl back into my hole at Sirius and lick my wounds," he said. "If it does work, I'll be thrilled."
