America's Got Talent: What Did Howard Stern Call "Highly Offensive"?!

Yes, there actually are certain things that make the controversial radio host squirm

We would guess that Howard Stern is really enjoying his new gig at America's Got Talent.

On tonight's episode, he got to experience a variety of noteworthy and not-so-memorable acts, but one in particular caught his attention—and not necessarily in a good way.

What in the world could Stern possibly find "highly offensive"?

"Air sex," that's what.

A man who claimed to be an expert at air sex proceeded to show the judges and audience how to act out this intriguing talent, which, when it came down to it, was basically acting out an intense makeout session with an imaginary person (the magic begins at 1:35 in the clip).

As you can probably guess, Air Sex man didn't move on to the next round.

But what you probably didn't see coming was Big Barry, and we're not just saying that because he's 4'10". The "70-year-old teenager" entertained everyone with a song. However, we hate to say it, but Big wasn't very good.

Stern was ready to buzz him outta there, but Howie Mandel talked him out of it and now Big Barry is going to Sin City.
