Newark Mayor Cory Booker talks briefly with Morning Joe’s Louis Burgdorf before Joe and Mika take over for him in the green room.

Bernie Madoff whistleblower Harry Markopolos speaks with Morning Joe's Louis Burgdorf about how he stays mentally fit, and how he keeps safe the identities of his whistleblowers.

Director, actor, Spinal Tap and Simpson's legend Harry Shearer talks with Morning Joe's Louis Burgdorf about his morning routine, not eating lunch. Louis even gets him to bring out Mr. Burns for a minute, and Shearer also mentions why Derek Smalls would never use a cucumber.

Def Jam co-founder and the RUSH Philanthropic Arts Foundation's Russell Simmons talks with Morning Joe’s Drew Katchen about the 12^th annual Art for Life benefit, practicing yoga and the legalizing of same-sex marriage in New York.

Quick bit of editorial housekeeping: I asked Russell his thoughts on the legalizing of gay marriage in New York, but my wording was a bit off. I asked him his thoughts on “Monday's marriage ruling.” Obviously, the ruling legalizing gay marriage happened in June, and same-sex unions began this Sunday past and not Monday. Didn’t have enough coffee this morning.

John Goodman in the Morning Joe greenroom

And that's kind of all you need to know.

The Golden Globe-winning actor dropped by the show today to talk about the new season of "Damages," among other things. We also got him talking about how Lebowski fans still shout "WALTER!" at him from time to time.

I had the good fortune of photographing him before his interview in our greenroom, and he was absolutely gracious. I told him one of my favorite films was 1986's inexplicably odd and totally cool "True Stories," which stands as David Byrne's only foray into directing. If you haven't seen it, then by all means do so. Hey, it was good enough for Radiohead.

Comedian and host of "The Marriage Ref" Tom Papa talked to me today in the Morning Joe greenroom about why he's a robe guy, and why Keith Richards made doing heroin and cocaine seem so practical.

After today's show, I spoke with author Leigh Montville a bit further about Evel Knievel. If you missed his interview on the show, you can check it out here. (It's really great)

Montville told me that even though Knieval is the most famous motorcycle rider of all time, he really wasn't a great motorcycle rider. Apparently his size got in the way of his riding. Who knew?

After the show this morning, I spoke with TV legend Larry King about an old cliché that has stuck with him throughout his life, and waking up to a bagel every day and taking his kids to school.

And then I spoke with boxing champion and Olympic Gold medalist Sugar Ray Leonard about how he gets his "engine warmed up" each morning and why writing the book was cathartic and therapeutic.
