First lady Michelle Obama has never been shy about wanting America to get moving to get fit and healthy. To promote her "Let's Move" campaign on "Late Night With Jimmy Fallon" on Friday, the president's No. 1 gal proved that getting active can be fun and funny -- for both parents and their children.

In a segment titled "Evolution of Mom Dancing," the late-night host -- dressed up in a soccer mom outfit complete with brunette wig, khakis and a pink cardigan -- and Mrs. Obama busted out some hilarious aerobic dance moves. Among them: the "Go Shopping, Get Groceries," the "Just the Hands Part of 'Single Ladies,' " the "Where's Your Father? (Get Him Back Here!)" and several more heart-healthy struts that Mama Fallon couldn't keep up with.

During his monologue, the funnyman joked that there was so much security at his "Late Night" studio for the first lady that on his way in, he "was grabbed, frisked and groped -- then I was like, 'All right, Kathie Lee! Enough. I have to get back to work."

He also had a fun little fun at the Vice President's expense, saying of Michelle Obama's appearance, "I heard they're even letting Biden stay up to watch. Isn't that nice?"

Watch the full dance here:

Jimmy Fallon prepares the puppies for their Oscar picks.

Will "Zero Dark Thirty" nab top honors on Sunday night? Does "Lincoln" have the edge? Maybe "Argo" is the clear Oscar contender. Of course with "Django Unchained," Les Miserables," "Life of Pi," and "Silver Linings Playbook" all in the mix for best picture, as well as "Amour" and indie breakout "Beasts of the Southern Wild," it's just so hard to say.

So what should you do before laying down a bet in the office Oscar pool? Turn to the prediction pros, of course -- puppies!

Hot off the heels of their winning Super Bowl pick, Jimmy Fallon's favorite team of fluffy pups returned to "Late Night" Wednesday to make the call.

With nine shiny bowls of dog food to choose from, each tagged with the name of one nominated film, the pooches stormed the stage and … well, they ate food from the several of the closest bowls in an attempt to fill up fast. Hey, first and foremost, they're dogs.

But fear not, their Kreskin skills kicked in eventually. A couple of furballs zeroed in on one bowl in particular and made it official: "Argo" is destined to win!

Or possibly not. They're only puppies after all.

In what context is it acceptable to refer to "NBC Nightly News" anchor Brian Williams as Brilly Willy? Or Honey Bri Bri?

In the context of slow-jamming the news on "Late Night with Jimmy Fallon," that's what. The "Rock Center with Brian Williams" host returned to the "Late Night" stage and along with The Roots, broke down a complicated news issue, R&B style.

While Williams, Fallon and the Roots tend to be the stars of the slow-jam show, another member of the NBC family got a shout-out in the fiscal cliff breakdown -- TODAY's Al Roker. Roots member Tariq Trotter cleared up the United States' debt situation singing, "The United States clearly couldn't get any broker, gotta liquidate its assets, like Al Roker." 

Oh, yeah.

Classic comedy duo Abbott and Costello first had audiences howling at their "Who's On First?" routine back in the 1930s. But just because the name-game gag is old, doesn't mean it's lost its edge.

On Thursday's "Late Night," host Jimmy Fallon invited modern-day comedy greats Jerry Seinfeld and Billy Crystal (along with his regular "Late Night" pals Steve Higgins and A.D. Miles) to put a new spin on the still-funny joke.

To see how the revamped rendition stands up to the original, check out Abbott and Costello's bit below.

Little did we know that all we really want for Christmas is for Jimmy Fallon and his "Late Night" house band The Roots to put their own spin on a holiday song.

Fallon and the band teamed up with Mariah Carey and banged out a most-rad version of Carey's "All I Want For Christmas," complete with accompaniment by the greatest of classroom instruments: kazoos, xylophone, wooden clackers, a melodica, and of course, sleigh bells and actual kids.

If this treatment looks familiar, it's because last month Fallon and company teamed with Christina Aguilera for a similar backstage performance, using office supplies to perform her song "Move Your Body." And back in June, Carly Rae Jepson stopped by to have fun with her viral hit, "Call Me Maybe." And let the record reflect we are totally fine with the recycling of this idea. In an era where the only remix a song gets usually involves Auto-Tune, "Late Night" proves going back to basics can be the most fun. And who doesn't love an excuse to bust out the melodica?

Gobble this! Jimmy Fallon introduced his latest installment of "Robert Is Bothered," the Thanksgiving edition, on "Late Night" Wednesday.

Before revealing the clip, the comedian explained, "It turns out Robert Pattinson is really really bothered by a lot of things. This guy is so angry ... that a couple of years ago, he started his own website called RobertIsBothered.com just so he can talk about all the different things that bother him."

In the video, the late-night host, dressed as the actor's "Twilight" vampire, Edward Cullen, launches into a tirade about the holiday.

"Thanksgiving bothers me," Fallon-as-Pattinson-as-Cullen gripes. "Thanksgiving is stupid! And which day is Thanksgiving anyway? All I know is it's the fourth Thursday in November. What kind of a day is that?! ... Well guess what, Thanksgiving? No particular date, no particular thank you!"

But it wasn't just the lack of a concrete date that bothered the imposter. Turns out he's not impressed by the traditional foods either.

"Turkeys are stupid, they bother me," fake Pattinson complains. "You murder a turkey, rip out its insides, then you shove a bunch of bread up its butt, and then you cook it for hours, then expect me to eat it and say thanks!"

He goes on to complain about other Turkey Day favorites: "Stuffing, cooked in a butt, not sanitary. Butternut squash, wants to be a pumpkin but it's not. Get a real job. Cranberries, too sour, no thank you. And here we go, mashed potatoes ... actually, I like mashed potatoes."

Check out what else Fallon-as-Pattinson-as-Cullen gripes about (but be warned, there is some salty-but-bleeped language):

This isn't the first time "Robert Pattinson" has complained about things. Past "Robert Is Bothered" videos have taken on the subjects of Snickers ads, "Harry Potter" star Daniel Radcliffe, Christmas, iPads and more.

Lindsay Lohan.

If acting doesn’t work out for Lindsay Lohan, she may have another career choice: hairstylist.

For her latest media appearance, instead of making headlines with a scandal, she chose a slightly more low-key role Wednesday night as Jimmy Fallon’s styling assistant.

STORY: A Plea on Behalf of Brainy Girls: Give Lindsay Lohan a Chance

Fallon stepped onto the stage for “Let Us Play With Your Look” in an all-white costume (complete with tights) and a short blonde wig. As he belted out the sketch’s theme song in as many inflections as possible, LiLo sashayed through the audience in a similar wig, all-white outfit and overly large cat glasses.

While the late night host continued his serenade, Lohan proceeded to play with a surprisingly compliant audience member’s hair. She heaped on the unsuspecting member a very questionable substance (butter, maybe?) and smeared in all over his hair and face. After massaging the mousse substitute into his scalp, Lohan settled on a mohawk.

After all the hard work singing, Fallon passed out onto a carpet, which was than dragged off stage, leaving a very confused Lohan all alone. With an awakward smile and some Vanna White-esque hand motions, Lohan slunk, or attempted to – she was hindered by a very stubborn curtain -- off stage.

Check out the comical cameo below.

The twenty-six year old Lohan plays Elizabeth Taylor in the upcoming Lifetime biopic "Liz & Dick" premiering November 25.

Fallon followed that one up with the trailer for "Lincoln," and now, he applies the same voiceover magic to Brad Pitt zombie disaster flick "World War Z."

If David Letterman and Jimmy Fallon crack wise and no one's around to laugh, are they still funny? It turns out ... yes, very!

With a massive storm approaching and New Yorkers being either evacuated or encouraged to stay in their homes, the "Late Show" and "Late Night" taped Monday  afternoon without audiences. (Maybe Letterman and Fallon should have tweeted their monologues, however -- thousands of East Coasters had lost power by the time the shows aired and local newscasts were providing constant storm coverage.) 

Lindsay Lohan dubs storm "Hurricane Sassy"

"We're in the middle of Hurricane Sandy and we have no studio audience," Letterman kicked off his monologue, before the storm had been reclassified, "but we do have quite a show for you tonight. Thank you for joining us in the Ed Sullivan Shelter."

He informed the, er, Paul Schaffer that Sandy was being tagged "one of the worst storms in U.S. history," and that experts were expecting 90 mile-per-hour winds and 12 inches of rain. Landfall was expected in Delaware and New Jersey at high tide, aided by the full moon. 

"If I were home, I'd be boarding up your television sets, because this is the stuff that's gonna hurt somebody," Letterman deadpanned. (Among the Top 10 Rejected Names for the Storm: Al Frankenstorm, Trumpical Storm, Wetzilla, iPaddle and Oprah Windy.)

Storm poised to pound stars' homes in the Hamptons

Soon after, unstoppable guest Denzel Washington showed up clad in a yellow rain slicker, as if he'd trudged through the streets of New York to be there.

"Only for you, Dave," the "Flight" star said. "I swam."

Asked if he had ever been in a hurricane before, Washington cracked, "Once, with Noah."

These celeb-owned homes in the Hamptons could be taking a beating

Fallon, meanwhile, ventured outside 30 Rock himself to do a cold (probably, quite literally) open.

"I'm hoping, if you're watching, you are at home, you're safe, you're warm.... But we're here," he added. Guest/storm troopers Seth Meyers, Padma Lakshmi, Robert Zemeckis and the band Imagine Dragons all made it, too. (Yes, it sounds like Fallon managed to get more guests than usual in the midst of a hurricane-powerful tropical storm.)

Slamming home the magnitude of the possible natural disaster looming outside, the camera panned to the nonexistent crowd (well, except for Mets bucket-hat guy) watching Fallon's monologue.

Frankenstorm's sideshow: Horse-headed guys, Mitt musings and Sandy sex

"Theater owners had to cancel all Broadway shows today," he said. "Many performers were having trouble making it into the city. You could tell by that one show, 'Blue Man Guy.'"

But Fallon and Letterman persevered. In repeats tonight, however, are the similarly New York-set "The Daily Show With Jon Stewart" and "The Colbert Report," as well as "Jimmy Kimmel Live" -- which tapes in L.A. but just happens to be in New York this week for a special run.

Tom Hanks sure has been making the rounds. Over the weekend he dropped by "Saturday Night Live," and recently he agreed to be interviewed by the Nerdist podcast thanks to a vintage typewriter being thrown in the mix. 

But he may have made his most surprising move Tuesday night, dropping by "Late Night with Jimmy Fallon" to do a poetry slam on ... the 1990s sitcom "Full House"?

Yep, it happened. Maybe he was inspired by the 25th anniversary party the "Full House" gang threw for themselves last month, maybe not. But it was almost certainly the longest (over 3 minutes) poetry slam late night has seen in years. 

Done up in full bohemian poetry guy duds (that is, a black turtleneck) and oh-so-serious demeanor, the Oscar-winning Hanks strode onto the stage and stood in a spotlight reading lines like: "House full of men/Danny, Jesse, Joey/Father, Uncle Friend/Uncle Jesse whose hair is never messy/Watch the hair, huh?/Have mercy on Uncle Jesse."

He even gave the whole setup a bit of a sinister twist, wondering why there were no women in the house, only girls.

"Late Night" guest Jerry Seinfeld and host Jimmy Fallon keep the laughs coming during commercial breaks.

Ever wonder what goes on at a live show taping when the host, guests, and audience all have to pause for a commercial break? Typically, it's an uneventful pause in the action. Makeup touch ups, chats with producers, reviewing of notes -- that's the norm. To keep the trains running on time, show production tends to be a pretty buttoned up affair, and the commercial breaks are no exception.

However, guests at a recent taping of "Late Night with Jimmy Fallon" were treated to a rare, amusing use of a break when Fallon and guest Jerry Seinfeld decided spend the time taking questions from the audience, and thereby showing off their improv comedy chops at the same time.

The first question was directed to Seinfeld, when an audience member asked, "Why won't you come to Israel?" After teasing about the question being a little "defensive," Seinfeld joked, "Because it's like seeing my relatives again. It's the same thing."

The next question went to Fallon: "When they do the movie 'Funny Boy: The Jimmy Fallon story, who do you want to star as you?'" "Assuming it's a musical," Fallon said of the questioners fictional film, "Hopefully one of the kids from One Direction."

To catch all the nuance and just and example of two good comedians at work, check out the above video for yourself.

Jimmy Fallon joined the cast of "Guys With Kids" for a rundown of TV's greatest theme songs on "Late Night."

In the grand tradition of Jimmy Fallon and Justin Timberlake's "History of Rap" (all three parts), the "Late Night" host gave another music genre a sound summary on Tuesday night's show -- with a little help from his friends.

Joined by the cast of "Guys With Kids," the sitcom co-created and produced by Fallon, he kicked of a "History of TV Theme Songs."

After lamenting the fact that many shows just don't have a true theme tune anymore, Fallon pulled out a microphone and began belting out the theme to "The Jeffersons." Before long, Anthony Anderson, Jesse Bradford and Zach Cregger took the stage and contributed to the remarkable roundup.

They cycled through the TV greats, including the themes for "All in the Family," "Golden Girls," "Friends," "The Fresh Prince of Bel-Air," "Facts of Life," "Good Times," "Greatest American Hero," "Three's Company," "Sandford & Sons," "Full House," "Saved By the Bell," "Happy Days" and "Cheers."

Watch the clip above for the full salute to TV songs.

"Guys With Kids," which features a theme song sung by Fallon himself, airs Wednesdays at 8:30 p.m. on NBC.
