Bitter? Nah!

Conan O'Brien made a surprise appearance on Late Night with Jimmy Fallon last night ... and it was the first time the comedian has been back to NBC since his major fall-out with the peacock network back in January 2010.

Jimmy now works on the same New York City sound stage that Conan called home for sixteen years. "You know, I was out in New York, I decided to drop by and check out my old studio," Conan told Jimmy after the audience's cheers died down.

"You were here for sixteen years. And then what happened?" Jimmy quipped.

After a hearty laugh, Conan -- who is now based in Los Angeles -- replied:

"Don't you worry about that. You're a young guy ... it worked out fine. Anyhoo, I came by for a reason, which is I left something here, something important to me. And I haven't had it in a while and I thought since I'm here ... I can get it back. Is that cool with you?"

What was it? Conan's famous prop pup, Triumph the Insult Comic Dog. See how Triumph fared in the video above.

Reunited and it feels so good!

Nicole Scherzinger is officially awesome.

The new X Factor judge went on Conan last night in a very tight leopard print dress that left very little to the imagination ... especially when it came to her cleavage.

Conan O'Brien tries to concentrate during the interview, but his eyes begin to drift downwards when she starts talking about why all the ladies love Simon Cowell. So she says, "Focus, Conan," and directs him back up to her face. "I'm trying to speak here," she laughs. "Serious talk."

How does Conan respond? "It's so [unfair]. I'm sorry! ... Good god! Finally let's be real here for a second. You didn't think I was gonna look down there?" And then he proceeds to mock-motorboat her.

Brilliant.

See the whole interview -- including her impressively dead-on Britney Spears impression -- above.

Conan is gearing up for the release of his upcoming big screen feature Conan O'Brien Can't Stop.

In the documentary, the former Tonight Show host reveals his very public and dramatic exodus from NBC. Also featured in the film, behind the scenes footage of O'Brien's 32-city music and comedy show Legally Prohibited From Being Funny On TV Tour.

O'Brien landed a show on TBS after spending only eight months as host of NBC's Tonight Show. Find out when Conan's movie will debut ... after the jump.

Conan O'Brien can't stop talking about getting the ax from NBC last year, and his latest rant is splashed in the new issue of Fortune magazine. On being replaced by Jay Leno as the host of the Tonight Show, Conan says, "You know that scene in the first Indiana Jones movie where he gets thrown through the truck windshield by a Nazi? I was thrown through the windshield of broadcasting."

Conan continues, "I made a decision and that decision very quickly led to me walking away from the crown jewel of old broadcasting and, in addition to that, being legally prohibited from going on television. Ten years ago, if my situation with NBC had unfolded, none of this would have happened. Yeah, maybe I was 10 years too late to do The Tonight Show that I wanted to do. But I was just in the nick of time. Do you know what I mean?" Um, we get it. Maybe now that you have a show on TBS it's time to move on and find something else to complain about?

But he's not done yet! Conan also revealed that NBC was annoyed he joined Twitter, telling the mag, "Tell them I would be thrilled if they shut down my Twitter account. I'd love it if that got out. You think PR's been bad up till now? Wait till you take away my Twitter account."

TBS

Uh-oh, this looks familiar.

After a little over a month on TBS, Conan O'Brien's ratings the fifth week of his show were the lowest since the show's debut, especially in his key demographic. What happened to all the "I'm with Coco" fans? Was that just a phase?

At this point O'Brien has lost more than half the audience who made up his premiere week, and if ratings keep slipping, we may see a repeat of last February when NBC booted him for the very same thing? At least Leno won't be behind him to take his place! Maybe he should just stick to comedy tours and his Twitter account ...

Either way, O'Brien walked away from one cancelled show a multi-millionaire. We don't think two will hurt him money-wise, but we do feel bad for all the crew that has moved from NYC to L.A., and now possibly back to NYC, if the show were to get the axe after just one season.

Bold move, Conan! Tom Hanks - who apparently gave the talk show host the nickname "Coco" - got doused with a bucket of water on O'Brien's TBS show last night when the ocean backdrop suddenly came to life with whales... and real water.

Thankfully Hanks is the nicest guy in Hollywood so he didn't seem to mind, but damn! Risky move. Watch the interview above!

Conan O'Brien debuted his much-anticipated TBS show last night to stellar numbers. In fact, ratings were so good that he beat out his fellow competitors Jay Leno, David Letterman and Jon Stewart.

The premiere of Conan, which featured Seth Rogen, Lea Michele and Jack White, was watched by 4.155 million viewers total, while Conan's nemesis Jay only rustled up a measly 3.5 million viewers.

The premiere ratings are all the more impressive for a show on basic cable. Way to go, Coco!

Conan O'Brien truly delivered tonight on the premiere of his TBS show Conan, and from our favorite bear to a snarky (but somewhat tame) opening monologue, we couldn't be more thrilled about his return to television.

When he started off the show, O'Brien joked, "Welcome to my second annual first show ... People ask me why I named the show Conan. I did it so I’d be harder to replace. This is an exciting night. I’m glad to be on cable. The truth is, I’ve dreamed of being a talk show host on basic cable ever since I was 46."

Conan continued, “A lot’s happened in the news since I went off the air — and I was hoping I could cover it all in one joke. But then I realized that’s like trying to keep an Icelandic volcano from wearing Lady Gaga’s meat dress while a trapped Chilean miner cleans up the BP oil spill…Brett Favre’s p*nis.” Immediately after this we got a peek at the infamous masturbating bear, and over the course of the rest of the show Conan chatted with guests Seth Rogen, Glee's Lea Michelle and he even jammed with musician Jack White. Take that, Jay Leno!

Can't wait to see what kind of numbers the red-headed comedian brought in tonight. Did you guys love it as much as we did?
