Fifty percent of the Fight of the Conchords appeared on Jimmy Fallon's show last night and Jemaine Clement talked about how the duo is treated in their home country. Apparently, they're known as "those guys" that are famous in America.

Last night, Jimmy had some fun with Twitter's hashtags and asked "Why don't they make that?" Some responses were pretty ingenious, but Jimmy was puzzled by a "Falcon Punch". I guess he's never played any Super Smash Bros.

Recently, we wondered whether a Facebook post by Martha Stewart contained a dick joke. Tonight, Stewart sat with Jimmy Fallon and—in between talk of travels and an orangutan she befriended—she confirmed (and repeated!) the phallic wisecrack. Video inside.

Heidi Klum was on Jimmy Fallon last night and the host wistfully submitted to letting her dissect his past red carpet fashions. Turns out the SNL alum stumbled upon some forward-thinking trends, but not enough to stem the fashionista's criticisms.

In a clip from Late Night, Jimmy Fallon as Robert Pattinson rants about things that bother him. In today's clip: the World Cup. Just in time for the United States to maybe advance to the next round!

Nearly three months after the last time he appeared with Jimmy Fallon on Late Night to "slow jam the news," Brian Williams stopped by tonight to participate in a musical number about renewable energy... and bi-curiousness. The chuckle-worthy video, inside.

Once it was announced that the Roots would be the house band for Jimmy Fallon's new show, all doubts that it would be awesome were erased. See why in this funky video/drum/turntable mashup.

Last night on Jimmy Fallon, The Roots played their newest music video "Smiley Face, Apple Sauce," but despite the song's feel good lyrics the tell all making of video reveals the tumultuous creative process.

Cedric the Entertainer talks with Jimmy Fallon on Late Night about a new iPhone app he wants to see in the near future. This may turn out to be the best selling app ever.

Last night on Late Night with Jimmy Fallon, Joy Behar talked about how she loves having hookers on her show and sung a little ditty about Spitzer's fondness for them as well.

The hosts residing in the 12:35 AM time slot took time out of their shows last night to declare a truce on the Late Night Wars using over-sized Mickey Mouse hands. Isn't nice to see them getting along?

Last night on Late Night with Jimmy Fallon, Glee star Chris Colfer tells Jimmy and Molly Shannon why he's on bad terms with Paramount Security and about a little accident he had on the lot.

"Don't swim in the ocean, you'll get [tar] balls in your mouth," sang Fallon during Friday night's Late Night broadcast. Despite the humorous tone, the song of protest resonates with those of us angry about the spill.

What started as a normal dance number ended with both men getting up in the grill of a perplexed audience member. She should feel lucky, as not many people get to be blown on by a super sexy megahunk.

Last night, Jimmy "showed a clip from the 1994 movie Space Train." In other words, he and Ben Kingsley put on silly costumes and performed the sketch live—and then continued the interview in full space garb.

"This isn't your father's SNL movie," advises Forte while his Mother watches in Jimmy Fallon's audience. He continues, "It's an R-Rated movie... a hard R" and then treats us to a rapid-fire swearing storm. I laughed my entire way through.

Jimmy can't wait until Sunday to figure out all of the island's mysteries. Kate or Juliet? Jacob or the Smoke Monster? Jack with a beard or without? Matthew Fox answers as best he can.

Jimmy Fallon showed us another entry in Robert Pattinson's personal vlog, "Bothered", last night. He sure hates that iPad. No word yet on whether Jimmy will have to apologize like Ellen did.

We hope you're all as excited for this movie as we are. Kristen Wiig was kind enough to shed insight into the filming process and her sex scene with Grubes himself. Bonus: one-second trailers created by Jorma Taccone.

There's not much to say here besides this: inside, you'll see a video of Betty White. In the aforementioned video, White plays beer pong with Jimmy Fallon. Who wins? Who gets wasted? You'll have to watch to find out. Huzzah!
