Damon Lindelof and Carton Cuse dropped by Jimmy Kimmel Live last night to announce the day the show will end its run: Sunday, May 23rd. Then they all joked about a "Hurley and the Smoke Monster" spinoff. Which we'd watch.

Yesterday, Jay Leno told Oprah Winfrey that he was "sucker-punched" by Jimmy Kimmel when Kimmel appeared on his show and took him to task over the NBC late night fiasco. Last night, Kimmel told the real story behind the setup.

Jimmy Kimmel's show seems to be a great venue for actors that are struggling with their image. The most recent celebrity to jump aboard the "revitalize my career and make me hip with the kids" train is Mel Gibson.

Historically, Jay Leno hasn't shied away from speaking about his job status. Leno's statements over the last few weeks—full of jokes about NBC, Conan O'Brien and David Letterman—reinforced that characteristic. Recently, however, he's been unusually mum. What gives?

Conan O'Brien just closed out his final episode as host of The Tonight Show, and what a show it was: hilarious shenanigans, Steve Carell, Tom Hanks, Neil Young, a tearful statement of gratitude, and Will Ferrell with a mothereffing cowbell.

In case you missed it, here is the full "documentary" that Jimmy Kimmel aired on his show last night. If nothing else, it's worth watching for the artistic interpretations of Conan, Andy, Leno, and Jeff Zucker in historical colonial dress.

If it wasn't clear before, it is now: David Letterman hates Jay Leno. Letterman repeatedly destroyed Leno on his show tonight, implying he's a thief and all-around bad guy. And while O'Brien made fun of NBC, Leno took personal digs.

Following yesterday's late night melee, we wondered: after four nights of infighting, would détente emerge this evening? Nope! Conan O'Brien embarrassed NBC in the best way ever, Jay Leno personally attacked David Letterman, Jimmy Kimmel mocked everyone, and much more.

Jay invited Jimmy Kimmel to the show to take part in his 10 @10 segment. Kimmel did not hold back his distaste for both NBC and Leno, going so far to say "For God's sakes, leave our shows alone!"

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.

One of Kimmel's best features is taking a clip, and bleeping or blurring it to take it wayyyy out of context. This is the best of the decade, and yes, it involves Grover receiving a handjob.

This ad came on during the Oscars and we're still baffled. It starts with Tom Cruise and Jimmy Kimmel in a steamy, tumbling embrace in Cruise's bedroom. Then it gets weird.

Ideally it would have been great to see Jimmy Kimmel come out and cut Nightline's throat in his just-released interview with Broadcasting & Cable. But! There remain some jagged edges in his late-night diplomacy.

Having already made it clear that he was less than amused with Andy Samberg's take on him as an amateur goat-whisperer from the mean streets of Mass (an impersonation we've hailed as pure genius—but Marky, if you're reading this, we hated it!), Mark Wahlberg upped the stakes considerably on a Jimmy Kimmel Live! appearance last night.After Kimmel ran a clip from the offending sketch, the actor—in a studied bit of business borrowed from any number of Scorsese-DeNiro collaborations—fastidiously plucked a stray thread off his dress shirt as he pledged to "crack [the Hot Rod star's] big fucking nose." The only thing better than a celebrity feud is a celebrity feud with lightly anti-Semitic undertones and the potential of skull fragmentation. Still, we think his tough-guy bark is worse than his bite, and Samberg needn't start truly panicking until Wahlberg pledges, in a clever twist on one of Samberg's greatest hits, to deliver the young comic his own nuts in a box.

Aspiring celebrities about to make your first rounds on the talk show circuit, take note. Earlier this year, we cautioned you regarding the pitfalls of repeating the same anecdote word-for-word on multiple talk show appearances, using Jason Segal's penis-bearing fable as our example. Tonight, we'd like to walk through the subtle art of how to recognize what kind of stories are good for dinner parties versus those that are suitable to be told to a national television audience, showcasing Mad Men star Jon Hamm's disastrously disrespectful appearance on Jimmy Kimmel Live! on Friday night.In this clip cut together by our very own Molly McAleer, you'll see two sides of the very same story coming together and then exploding before your very eyes. Here's a quick primer. You see, Mr. Don Draper himself, Jon Hamm, appeared on the Live With Regis And Kelly show on Thursday morning. Little did he know, both Regis and his wife are huge fans of the show Mad Men. They're such big fans, in fact, that the 77-year-old Regis thought it would be fun to spend a little time after the show with Hamm, going as far as to invite him over to the Philbin's apartment. Being the good sport that he is, Hamm agreed to hang with Reege and Joy for a few hours, posing for pictures and making small talk until other obligations rescued him from what was undoubtedly an awkward situation. Up until this point, it was a win/win for all parties involved. Hamm endeared himself to a showbiz legend and Reege got to hang with an actor who likely reminds him of his 1960s glory days. (As you'll see in the clip above, Regis is still beaming four days later.) However, Hamm submarined himself by being unable to hold his tongue about how he really felt about spending time with the Philbins when he came on Kimmel's show on Friday night. Rather than save the story of Regis' wacky behavior for the afterparty in the green room of the El Capitan, he made the cardinal mistake of derisively referring to one of Hollywood's most endearing and popular fixtures as "an elfin force of nature" and a "crazy showbiz guy." Boo! Jon, we know your intentions were in the right place. You were on your friend's show, you had a great story and you just wanted to make the audience laugh. However, poking fun at a beloved institution like Regis is miles apart from poking fun at a tired old windbag like, say, Larry King. Save the barbs about how "crazy" Regis is for when you're kicking back with a few beers at your buddy Kimmel's house, versus sitting on his chair with cameras trained on you and millions thousands of people watching. If you want your career to have legs, that's a lesson you'll want to learn sooner rather than later.

Yesterday, we noted a Gawker item suggesting that Molly McNearney, who swiftly ascended the Jimmy Kimmel Live! ranks from lowly Chinese Theater Chewbacca-wrangling assistant to that show's head writer, had been the woman who came between Kimmel and Sarah Silverman. A Defamer tipster who knows McNearny wrote us to say this couldn't be further from the truth:

The battle this spring between hands-on artiste Ed Norton and the Marvel Studio brass over the relaunch of the Hulk franchise has proven to be one of the most acrimonious displays of "creative differences" that we have seen in some time. The notoriously "passionate" (read: difficult) actor has been accused of "posturing" over how the final cut of the movie he famously claimed to have re-written played out, which led to a brisk retort written by Norton and emailed to, of all places, the actor-friendly confines of Entertainment Weekly. And although accuracy-challenged scribe Roger Friedman reports that Ed Norton "slipped off to a desert island rather than do publicity for the movie he stars in and nominally wrote," the cantankerous diva appeared in a Hulk promotional parody skit that aired on last night's Jimmy Kimmel Show. And while Norton brought the funny, he didn't resist the urge to get in a potshot at action-averse auteur Ang Lee.

Jimmy Kimmel Live started out with a bawdy jibe about fathering a teenage Spears lovechild—a gem likely polished to perfection while lying in a bathtub and staring at two hairy kneecaps protruding from the milky water—but then things took a serious and controversial turn: After offering his audience a primer on what it is strikers are asking for (free internet access), Kimmel said that he didn't want to "depart too much from the party line," then proceeded to board a Party Line Getaways Jet Tours Adventure, railing against "ridiculous" picket lines and SAG's blacklist bullying of potential guests, before demanding that the public "run down these weasel-faced Commies" until their "red insides fill your tire treads." Then he turned to deadpan security guard Veatrice for her take on the labor unrest.
