Did you know NBC’s Lester Holt hosts a Sunday political talk show? And that you are required to wear tank tops during all debates?

Jimmy Fallon revealed this by showing a recent argument he and Ed Norton had on the show.

If you turned on the television last week then you probably noticed that The Town’s press tour brought Jon Hamm on just about every single talk show imaginable. He was on the Daily Show, he talked with Bill Maher, heck, I’m pretty he sure even travelled back in time to discuss Ben Affleck’s directing style with Dick Cavett. However, it was during his appearance on Late Night with Jimmy Fallon that we learned this disturbing secret: Brian Williams is stalking him.

MSNBC’s Rachel Maddow took the 30 Rock elevator up a couple floors last night to be a guest on Late Night with Jimmy Fallon.

Now in the lead guest seat, a show of how far she’s come in the mainstream non-cable news entertainment world, Maddow talked about the “bad name” for the next phase of Iraq and her busy month of travel for work – that saw her ratings decline.

Late night comedy television has consistently been a location for heated competition – recently, more so than ever. (“Late night wars” has to be one of the most populated non-cable news tag pages on Mediaite.)

But this week, Jimmy Fallon and Craig Ferguson did their parts to end the wars and become BFFs.

Jimmy Fallon‘s trailblazing new media innovation presence continues next week with a late night first – each night he’ll live stream from his office while that night’s show airs at 12:30amET.

Mediaite talked to Late Night Supervising Producer Gavin Purcell about the decision and what fans can expect.

While The Tonight Show with Jay Leno will be cross-airing on the Sarah Palin Network, the other NBC late night comedy show, Late Night with Jimmy Fallon has been thriving in another arena as well – on the web.

Thursday night’s show was a perfect example – jam-packed with viral videos rarely seen among the current crop of late night shows.

Late Night with Jimmy Fallon served up two doses of NBC-crossover viral videos last night, as NBC Nightly News anchor Brian Williams helped “Slow Jam The News” while Jeff Goldblum helped perform a Law & Order-related musical number.

Check it out:

Jimmy Fallon‘s version of a late night show involved viral video hits, SNL-like sketches and more that are the result of his personal history at Saturday Night Live as well as his executive producer, Michael Shoemaker.

Which last night meant his nightly Late Night show got the first crack at a sketch involving tickle fight enthusiast Eric Massa.

Back in 2005, the first viral video hit that put Saturday Night Live‘s Digital Shorts on the map was “Lazy Sunday,” which touted the virtues of the Chronic(…les of Narnia).

With former SNL cast member Chris Parnell a guest on Late Night with Jimmy Fallon, the taped short was performed live for the first time last night.

NBC Nightly News anchor Brian Williams appeared on Late Night with Jimmy Fallon Friday for an interview segment as well as a cameo with The Roots and Fallon during their regular “Slow Jam The News” sketch.

“Brilliams” talked budget in song, and joked about NBCU’s problems during the interview.

Today we attended a press conference and preview performance for Ringo Starr‘s appearance on Late Night with Jimmy Fallon tonight. The former Beatle will be the only guest (and of course, musical guest) on the show, and he, Jimmy Fallon and Ben Harper (playing along with Starr’s band) spoke to members of the press today.

Here’s a look at what went down.

The new hot late night TV rumors involve The Jay Leno Show being moved back to Leno’s former 11:30 time slot, rather than scrapped entirely. For some reason, however, this didn’t stop Leno from still talking last night like cancellation was still in the cards. And NBC seems entirely to blame. Video inside!

Jimmy Fallon stormed into the Today show studio last Wednesday morning decked out in pink Uggs and pink vest, skintight white pants, a wig and make-up. Hoda Kotb, Kathie Lee Gifford and other Late Night writers crossdressing for the taping of the “Real Housewives of Late Night” sketch couldn’t hide their amusement.

It’s the latest example of the dual TV/web role of Fallon’s new show – and another reason why his program is a model for the future of broadcast TV as a whole.

Sometime between his monologue and his first guest, Jimmy Fallon of NBC’s Late Night offers up some Saturday Night Live-like sketch comedy. The segments draw viewers and non-viewers alike to NBC.com and Hulu, and some have hit and become viral video sensations. Here’s Fallon, as Neil Young, singing the theme from Fresh Prince.

Jimmy Fallon found probably the most unique way yet to talk about the biggest story of the week: Sarah Palin‘s book.

Last night on Late Night, “Going Rogue” literally went rogue.
