It’s been a busy Tuesday for Bill Murray.

You don't just walk away from a Lawrence O'Donnell interview — especially when he hasn't started asking you anything yet. When George Zimmerman's lawyer Craig Sonner canceled his appearance on The Last Word at the very last-minute, Lawrence O'Donnell decided to interview the chair where Sonner would have sat.

On Monday night's Last Word on MSNBC, Lawrence O'Donnell paid tribute to legendary director Sidney Lumet, who died in April and was memorialized at Lincoln Center on Monday afternoon. He did it by playing clips from some of Lumet's most memorable movies, but when the tribute got to a scene of Philip Seymour Hoffman from Before the Devil Knows You're Dead, the audience was treated to an unedited F-bomb—and a good one at that! Video of the entertaining oversight is above. [via Business Insider]

When MSNBC rolled out its new slogan "Lean Forward" last year, it was a transparent attempt to beat Fox News at its own game. (That game, for the record: news as partisan propaganda.) This is the only idea that MSNBC has. You can be sure of it, because Jeff Zucker denies it.

MSNBC's Lawrence O'Donnell plagiarizes not only Katie Couric's questions, but also her "serious face." Watch the Couric-Palin/O'Donnell-Johnston interview side by side. Also note the similarity in Palin's and Captain Knock 'er Up's responses.

Wasilla, Alaska mayoral candidate Levi Johnston appeared on Lawrence O'Donnell's new MSNBC show last night to answer a classic question set: Those that Katie Couric stumped his baby's grandmother Sarah Palin with two years ago. Levi fares... about the same!

Have you ever asked yourself, "Is there anyone who doesn't love Snooki?" I have, and I could never answer, "Yes!" until this morning, when—during a Morning Joe discussion on education—Lawrence O'Donnell hated on the Princess of Poughkeepsie.
