Michael Cera visited Late Night this evening (after raiding his grandpa's closet) for a chat with Jimmy Fallon about a variety of topics, including his day with the Jersey Shore cast. Also discussed? Cera as King of the Photobomb.

During an interview segment with Fred Willard on Late Night with Jimmy Fallon this evening, things got pretty awkward for a second when it appeared as though Fallon took a dig at his predecessor, Late Show host David Letterman.

Tonight's episode of Late Night with Jimmy Fallon was packed with goodness: The Real Housewives of Late Night finale and a cute interview with Joy Behar, for example. But Fallon saved the best—a performance with The Muppets—for last.

Tonight's episode of Late Night with Jimmy Fallon will feature the "season finale" of one of the show's best sketches, The Real Housewives of Late Night. Last night, Fallon aired a "Bonus Footage" precursor to tonight's big event. Watch inside.

The Strokes' Julian Casablancas performed his holiday single "I Wish It Was Christmas Today" on yesterday's Late Night. A newly-trimmed-down Horatio Sans and Jimmy joined him onstage, dressed in the same holiday sweaters worn in the original SNL sketch. Awesome!

Martha Stewart dropped by Late Night with Jimmy Fallon tonight for two segments. The first: an interview with Fallon, in which Stewart's intrinsic pretentiousness played out hilariously. Later, she and Fallon made croquembouche (and penis jokes). The videos, ahead.

Did you hear? Digg founder Kevin Rose was on Late Night with Jimmy Fallon Wednesday. As was Rose's forgettable Diggnation cohost — what's his name? Ah, yes — Alex Albrecht, who we hear wants out.

Blue? Just read Twitter, and you'll feel better. Jimmy Fallon's producer cried from fatigue. So did a Gizmodo blogger. An ABC news guy's biggest accomplishment? Going to the DMV. The sad life of Twitteronians:

Awkward or not, Late Night with Jimmy Fallon's fairly decent premiere last night got solid ratings, beating his rival Craig Ferguson. He also improved on Conan's average, though that won't last long.

Unlike the rest of you, probably, I'm still watching Jimmy Fallon's webisode things that are leading up to his taking over Conan's Late Night desk on Monday. And, I gotta say, he's growing on me.

Today's tweets: Ashton Kutcher tried to be more tolerant, the New Yorker's Sasha Frere-Jones tried to be more zen, and a guy who dropped out of journalism school tried to be more drunk.

Even in commercials, you'll never escape Jimmy Fallon. [B&C]
