Bill Murray hobbled out onto Letterman last night in crutches, shorts and a parka to do an "interview", but it was more like two comedic masters trying to outweird each other the whole time—and it was hilarious.

In a couple of hours, Jay Leno returns to The Tonight Show. I will be tuning in. Why, you ask? Because I used to actually like Leno, and—honestly—I'm not sure that I ever really stopped. Inside, I explain.

White Castle is, without a doubt, the most depressing fast food chain out there. Lifeless white walls, sad, grayish burgers, and unhappy employees. Everything about it just screams depressing dining experience. Last night's Undercover Boss confirmed this.

After two Chile-riffic episodes, the teams finally made their way to another country! All they needed was to take a "scenic, six-hour" bus ride through the Andes into Bariloche, Argentina. And the challenges had the cowboys written all over them.

Tonight's episode of SNL was a bore until this: a hilarious, celebrity-centric spoof of CBS' Undercover Boss that featured Steve Jobs as a trash man (you know where this is going), Richard Branson, Martha Stewart and more. Video inside.

This week, the racers were headed to Puerto Varas, China Chile. Carol & Brandy and Joe & Heidi formed an alliance-and pissed everyone off when they cheated the line, ensuring they'd be the only teams on the first bus out.

Trash company Waste Management's executive was featured on CBS's advertainment pseudoshow Undercover Boss. Today: the company announces fourth quarter profit rose 45%. Plus: companies were "given assurance that the show wouldn't damage the brand." CBS: American capitalism's last friend!

Survivor has returned for its TWENTIETH season. It hasn't quite jumped the shark yet, because the first 15 minutes had me laughing maniacally. But as far as the show itself, Survivor is pretty much copying MTV at this point.

After the Super Bowl was over, CBS premiered Undercover Boss, a role-reversal "reality" show where a big-wig performs entry-level tasks. Larry O'Donell, COO of a Waste Management Company, performed some nasty jobs, and many (faux) lessons were learned.

You think it's easy getting Oprah Winfrey, Jay Leno, and David Letterman in a room together to tape a 15-second gag for the Super Bowl? Then you're wrong! This thing took private jets, corporate rescheduling, even espionage!

File under: WTF and DIDN'T SEE THAT COMING. Remember the Late Show ad starring David Letterman and Oprah Winfrey that aired during the 2007 Super Bowl? Well, they just did a reprise... with the addition of Jay Leno. Video, inside.

After a light 237 hour pregame show, the Super Bowl is finally here. And while there is an actual game to be played, we're here to catch all the awkward live moments and best commercials throughout the night.

History-making news anchor Katie Couric—beautiful gin dancer, certified anchorbabe—recently did a fashion photoshoot for Harper's Bazaar and she looks faaaabulous. She's got legs for days and arms to rival Michelle Obama's. (Mud wrestling, ladies?) Observe some video stills.

It appears that someone wants to turn Anna Wintour's fake charity Fashion's Night Out into a reality show. The only way a whole evening of shopping is going to be exciting is if there are some challenges. Some ideas!

This year's Grammy Awards actually deserved the "Music's Biggest Night" title. Inside, video of all the best moments, including Lady Gaga's opening duet with Elton John, a speech by Michael Jackson's kids, and performances by Beyonce, Taylor Swift and more.

Moments ago at the 52nd Annual Grammy Awards, Stephen Colbert presented the award for Song of the Year. One problem: he couldn't find the list of nominees. The Colbert solution? Look them up on the iPad! The hilarious video, inside.

Have you seen a "Whose side are you on?" poll related to the Late Night Wars recently? Did you notice the small number that reflected support for Jay Leno and wonder, "Who are those people?" Well, wonder no longer.

CBS is waiting to come to a decision about whether or not to air a graphic ad for gay dating site Mancrunch. After allowing Tim Tebow's spot dissing abortion how can they say no?
