The newly crowned Miss Universe, Jimena Navarrete, presented tonight's Late Show Top 10 List, "Ways Miss Universe Plans to Make the World a Better Place." Unfortunately, along with a couple of great ideas came a cheap shot at her country.

On last night's Late Show, Drew Barrymore was busy telling David Letterman about her perfect pooches when, suddenly, he started to roll up his sleeve, revealing several scars/bite marks that he says came from Sully, his "Satan" dog. Video inside.

Tonight, David Letterman welcomed Brian Williams to his show. For the first four minutes of their chat, Letterman did nothing but talk about Jay Leno—his voice, cars, etc.—and implore Williams not to appear on his show. Video inside.

Today at Gawker.TV, David Letterman takes a jabs at Brett Favre and Jay Leno, Will Ferrell and Jimmy Fallon reminisce about their SNL days together, everyone hates Michaele Salahi, and Sofia Vergara won't run down Sunset Boulevard in the buff.

Last night, David Letterman welcomed Rachel Maddow to the Late Show and—while discussing Shirley Sherrod/Andrew Breitbart—got uncharacteristically political, asking, "How much time was wasted by this asshole fucking around?" Shots were fired at Fox News, too. Video inside.

On yesterday's Late Show, David Letterman had some choice remarks for retired-but-possibly-not-retired Brett Favre, who may or may not be bluffin' with his muffin. Want a bonus? How about this: Letterman also worked in an anti-Jay Leno joke! Video inside.

Michael Cera went on Letterman to promote his new movie, but before doing so he spoke vividly about his trip to Denver that nearly cost him his life. Never climb mountains at night kids. NOT COOL!

Today at Gawker.TV, Will Ferrell and David Letterman hop in bed together, Stephen Colbert thinks he's gay, The Bachelorette finale, talkin' politics with Basil Marceaux, and Whoopi Goldberg attacks Radar Online for releasing the now-infamous Mel Gibson tapes.

On the Late Show, Will Ferrell informed Dave of next project—taking over Caterine Zeta-Jones' role on Broadway. Skeptical? Watch this "impromptu" performance complete with a bassoon and finale consisting of the host and Ferrell in bed together.

Sorry ladies (and interested dudes), Paul Rudd's already married with 2 kids, and on the The Late Show, he elaborated on his tooth fairy excess and how he might have ruined other children's fantasies forever. Way to go, Rudd.

Kristen Schaal stopped by the Late Show last night and reminisced with Dave about her rural upbringing, move to New York and the crappy job she took to finance her eventual rise to fame and awesomeness.

During filming of yesterday's Late Show, David Letterman stopped traffic outside of his studio to play a round of baseball with Cardinals' Albert Pujols and male-hero Denis Leary. Wonder if those buildings or cabs mind being pummeled with random baseballs?

For years, David Rees wrote the amazing clip-art comic Get Your War On. Now he's launched a service where you can send him your pencils and he'll sharpen them. Also: a campaign for him to sharpen pencils on Letterman.

In support of Mayor Bloomberg's ingenious idea to convert old garbage dumpsters into recreational swimming pools, Bill Murray christened the experiment on the Late Show tonight by going for a quick dip. Going green shouldn't mean turning your skin green.

There was a time in Steve Carell's life before he was the beloved Michael Scott or even a 40 Year Old Virgin, and just a college graduate with a pervy moustache and a fife-playing Red Coat in the Revolutionary War.

To promote Inception, Joseph Gordon-Levitt paid David Letterman a visit last night. After Dave asked about his family, JGL discussed his brother's career as Burning Dan.

Joe Halderman, the CBS producer currently in jail for his ill-planned extortion attempt of David Letterman, has been nominated for an Emmy Award. Yea. True story. Yea—he's up against "Locked Up Abroad." [Laughter] Paul Shaffer, ladies and gentlemen! [TVNewser]

One night after M.I.A.'s disastrous Late Show performance, David Letterman welcomed "experimental performance artist" (according to her Wikipedia) Laurie Anderson on the program to, well, do some weird ass spoken-word/repetitive thing involving experts, problems, and the oil spill? Video inside.

Yes, people—even me, sometimes—enjoy making fun of Larry King. But tonight, David Letterman's Late Show Top 10 List—"Reasons Larry King Is Retiring"—was uncharacteristically harsh toward King, with multiple personal jabs at the sexxxy broadcaster. Video inside.

As we all know, soda + mentos = a good way to kill an afternoon. David Letterman has taken that formula and used it to offer us a new way to cure our nation's oil dependency. Suck on that, BP!
