You might date the end of the Late Night Wars from Conan's last episode of "The Tonight Show"...or Jay Leno's second first episode of "The Tonight Show." You may also find yourself musing on the question of who won or lost said Late Night Wars as you watch the clip above, in which Leno's time-slot rivals Jimmy Kimmel and David Letterman discuss their shared antagonist on last night's episode of "The Late Show." The rest of last night's late-night highlights are after the jump.

"The Tonight Show" had an interview last night with a guy who doesn't know how to let go of the career he loves. You see, this is a guy who's walked away from his passion, only to return to it a few months later. People say he's washed up, but he defies the odds and keeps trotting out to go to work whenever he's needed by his employers. Some people love the guy, others loathe him, but one thing's for sure: Matthew McConaughey was really pumped to be sitting next to Brett Favre during the above interview.

Oh, you thought I was talking about Jay Leno?

Last night, Jay Leno returned to the "Tonight Show" berth he'd vacated last spring; perhaps you heard or read something about how Conan O'Brien doesn't host that show anymore? How well did Vulture, MTV, and NPR's Monkey See blog predict what Leno would do in his first episode back at 11:35? You can find out by watching the full episode above; the rest of last night's late-night highlights are after the jump.

The Wrap reports today that newly bearded Conan O'Brien -- seen above on "Inside The Actors Studio" -- will star in his own touring road show in several cities across the country between now and September, when the terms of his NBC exit contract permit him to go back on the air. This is so exciting, I can barely contain my feet from slipping into tap shoes and improvising an elaborate dance routine of some kind. O'Brien is not only giving his "Team Coco"/Generation Pepsi-Dot-Com/"Kids Today with their XBoxes" fans a chance to see him live and in person -- which, based on the success of the "It's Always Sunny in Philadelphia" and "Family Guy" live tours, is a thing that young people actually like to go and do -- but his taking The Coco Show on the road is a genius way for O'Brien to get that ol' fashioned "pound-the-pavement" cred, the way Leno bragged to Oprah about doing his act in cities besides Los Angeles, so he could learn that some people don't like it when you're mean to George W. Bush.

I, for one, am just relieved I no longer have to wait until September to see Conan again; let's just hope they find room for Andy Richter, La Bamba, Wax Tom Cruise, and the Masturbating Bear in the Conan Road Show Van.

Last night on "Letterman," the cast of CBS's "Survivor: Heroes vs. Villains" braved New York's Snowpocalypse and read the Top 10 List. The cynics amongst us will sneer that it's fitting that a bunch of tired reality stars are participating in late night's most tired comedy bit (until Leno's "Tonight Show" inevitably brings back "Jaywalking," that is). But we are in a post-Coco universe, and cynicism is no longer acceptable! So, let's just point out that the new season of "Survivor: Heroes vs. Villains" premieres tonight at 8 on CBS; I, for one, am really looking forward to it. And hey, Rupert, neat tie dye!

My first thought watching the ad above, promoting "The Late Show with David Letterman," may have been the same as yours: were Jay Leno and David Letterman really in the same room? Because I spent the entire month of January (and a little bit of last week) watching Letterman absolutely eviscerate Leno over his re-taking of "The Tonight Show," and were I either one of them, I wouldn't necessarily want to hang out after that, even for the purposes of a TV spot. Fortunately, Bill Carter of The New York Times (the official documentarian of Late Night War I and II) has the story of how it all came together.

But...that's not the whole story. TheWrap.com reports exclusively that the initial idea for the spot featured the two late-night hosts and Conan O'Brien. Evidently, though, O'Brien is sticking to the spirit of his classy "Tonight Show" sign-off, which is a triumph for good manners but a tragedy for those of us who might have liked to see Jay Leno covered in guacamole and shame.

After Conan O'Brien said goodnight to his "Tonight Show" on January 22, I, for one, had a lot of anger, so for Conan's swan song not to be followed by a week of new episodes of "The Late Show" starring the only person in America that's more irritated by this whole situation than I am was a disappointment. Fortunately, Rosie O'Donnell was available to fill the gap. Find out how after the jump.

In yesterday's installment of Late Night Last Night, I mentioned that Jay Leno was about to appear in an hour-long interview on "Oprah." One topic that arose in their chat was Jimmy Kimmel, and the disaster that was Kimmel's infamous 10@10 segment on "The Jay Leno Show" two weeks ago. Once he saw what Leno had to say about it, Kimmel had to respond. See his remarks above, and click "continue reading" for the rest of last night's late-night highlights.

Sure, last night's TV was all about President Obama's first real State of the Union address, but since "The Daily Show" won't be covering that until its episode tonight, it was able to turn its attention in Wednesday's episode to other matters -- specifically, to a story about a plot to tamper with the phone in the office of Louisiana Democrat Mary Landrieu. See Jon Stewart's take above, and hit "continue reading" for the rest of last night's late-night highlights.

Today, from the "Wait, wait, WHAT?" file, comes news that Larry the Cable Guy will be starring in a new series on the History Channel. Now, if Larry's history lessons are anything like his child rearing tips (above), this is certainly not good news for people who like to learn about history. But for the rest of us, this actually could be pretty fun. Reuters explains:

"In 'Only in America With Larry the Cable Guy' (working title), Larry explores the country, immersing himself in different lifestyles, jobs and hobbies that celebrate the American experience." Gabe at Videogum followed that with his own deduction: "It's gonna be like 'Guy Fieri Road Show' but without all that sauce! Yuck." Though, I disagree with that last piece of commentary, and here's why:

This show is apparently going to be "Dirty Jobs," combined with "Diners, Drive-Ins, and Dives," and hosted by a character who should probably be in a home. I said character, because Larry the Cable Guy is actually a guy named Daniel Whitney, and he seems pretty normal. But, you know what? Who cares if he's not a real guy? I like the sound of a combination of "Dirty Jobs" and Triple D, because those shows are great (even if Guy Fieri isn't). Throw Larry the Cable Guy into it, and the result is less of a TV show, and more of an anthropological experiment. So far, 2010 is a brave, new world filled with "Conveyor Belt of Love." "Only in America With Larry the Cable Guy" is a giant step up from that.
