Conan O'Brien took to the airwaves tonight on the day he announced he'll leave NBC if he has to follow Jay Leno with another NBC/Leno-bashing broadcast. David Letterman, Jimmy Kimmel and Craig Ferguson joined in, while Leno stayed mostly quiet.

Conan O'Brien has officially gone rogue. On the heels of Friday's unusually harsh monologue, O'Brien went after the network that screwed him even harder tonight. Also: David Letterman and Craig Ferguson chimed in with some NBC/Leno digs of their own.

Today at Gawker.TV, Jimmy Fallon makes backhanded comments about David Letterman, the 31-year-old virgin who refuses to leave, not all contestants on The Bachelor have coordination, this week's Hoarder has lost a loaded gun in his house, and cowbell girl.

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.

Today at Gawker.TV, Betty White's a party animal, Little Chocolatiers has no business being on TV, Operation Repo highlights ways to get out of car repossession, Julian Casablancas gets down on Late Night, the best of Jimmy Kimmel's unnecessary censorship.

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.

Johnson & Johnson heiress Casey Johnson may have gone psycho for a model who likes to cling octogenarians; everyone obsesses over Tiger Woods' mistress; Westchester reprimands Richard Gere for chopping down trees. Tuesday's gossip ranges from sordid lechery to suburban ennui.

Say what you will about jimmy Fallon, the man can do good impressions. Here he is singing the theme song for The Fresh Prince of Bel-Air in complete Neil Young get-up.

Tonight Conan O'Brien takes over the reins of the Tonight Show and he'll probably score huge ratings because it's his first show and everyone will be curious to see what the new show looks like. But who are you going to watch at 11:35 after all the hoopla dies down?
