Jerry Seinfeld continues to generate massive amounts of free publicity and news coverage for his webseries, Comedians in Cars Getting Coffee, that puts all other comedian podcasts and webseries to shame, leaves them in the dust, has them crying for mercy.

And yet, for all of his fame and fortune, Seinfeld, 60, still feels discomfort. As he told Brian Williams in an interview broadcast on Thursday’s NBC Nightly News, Seinfeld thinks his own personality disorder would fall somewhere in line with Asperger’s or autism.

“I think, on a very drawn-out scale, I think I’m on the spectrum,” Seinfeld told Williams.

Why? Williams replied. What makes you say that?

“You’re never paying attention to the right things. Basic social engagement is really a struggle. I’m very literal, when people talk to me and they use expressions, sometimes I don’t know what they’re saying. But I don’t see it as dysfunctional. I just think of it as an alternate mindset.”

Roll the clip.

And here’s an exclusive backstage look at Seinfeld before a show, also from NBC Nightly News, showing how he prepared for a gig last month.
