If you’re in need of about five minutes of Chappie star Hugh Jackman and Tonight Show host Jimmy Fallon discussing, joking about, and sporting mullets, have we got a clip for you. Jackman stopped by the show last night to talk Chappie – all robots and future and stuff – but Fallon quickly fixated on his favorite element of the entire film: Jackman’s mullet. Turns out, Jackman went full mullet for the role, and it’s actually not the first time he’s grown out his own party in back/business in front coif.

It's the moment we all knew would happen eventually -- and, based on the immediacy of the news cycle and when late night shows are actually filmed, it's the moment most of us also knew was happening yesterday -- but 'Daily Show' host Jon Stewart has finally announced his retirement after seventeen years at the news desk. Stewart's show films in the late evenings in New York City, so the news that he had announced his imminent retirement during a taping last night hit the wire many hours before the show actually aired.

Well, almost the entire cast. 'Tonight Show' host Jimmy Fallon is really get into Los Angeles living during this week's sojourn to the land of sun and fun, and no ode to California would be complete without a loving nod to the ultimate Cali show: 'Saved By the Bell.'

Celebrities have feelings, too. Even when you think you're just talking random smack about them in the wide world of the internet (web?), you're still talking random smack about real people. If you're tweeting mean stuff? They might see it. And it might hurt them.

Jimmy Fallon's 'Lip Flip' must be stopped. It has to end. Sure, the technology that drives this particular 'Tonight Show' segment is vaguely impressive (there are lips! and then they get flipped!), and Fallon and his various guests appear to have a good time pretending to talk out of each other's mouths, but the final execution is so terrifying, so weird, that it can only do one thing: cause nightmares.

Did you really think that the blockbuster 'Taken' franchise was over with the release of last week's 'Taken 3'? Come on, you know better than that. We all know better than that.

Flashback! No, just flashing lights. Wait, wait, no, it's both! 'Portlandia' stars Fred Armisen and Carrie Brownstein hit 'The Tonight Show' last night to talk a little bit about their show's newest season (which starts tonight), which will apparently be heavy on the flashbacks and backstory. How did all of your favorite 'Portlandia' characters meet? This season just might pack a very special punch for you.

Kidman and Fallon have previously met—all celebrities know each other, obviously—but while Fallon remembered their years-ago hang as a sort of weirdly casual thing, Kidman recalls it a bit differently. For Kidman, it was a romantic prospect, and the look on Fallon's face when he realizes what might have been is genuinely priceless. You really blew this one, Fallon.

"Stephen, you've been taking a lot of shots at my job, I decided I'm going to go ahead and take a shot at yours." 'The Colbert Report' host Stephen Colbert has been teasing his biggest show ever for awhile now, including a stopover in Washington, D.C. and a long-form chat with President Barack Obama, but even he can't possibly have foreseen how that event would turn out. Essentially, it resulted in the talk show host losing his job...to President Obama, who swept on to stage and hijacked the show from an aghast -- but totally willing -- Colbert, only to put his own spin on what it means to host a political chat show. Does Colbert have something to worry about? We vote yes.

For his latest round of "Celebrities Read Mean Tweets," Jimmy Kimmel trotted out his most star-studded line-up of celebs yet, including Gwyneth Paltrow, Lena Dunham, Gerard Butler, Ty Burrell, Bob Newhart, Britney Spears, Geena Davis, Chris Pratt, Chloe Grace Moretz, Scott Foley, Michael Chiklis, Ted Danson (Ted Danson? who tweets mean things about Ted Danson?), John Stamos, Lisa Kudrow, and Adam Sandler. But he also rounded up the meanest collection of, well, #meantweets ever. These tweets are really mean, you guys!

"Everybody wants one!" In celebration (maybe?) of this week's long-in-the-making 'Dumb and Dumber,' star Jim Carrey decided to really spice up his appearance last night on 'Jimmy Kimmel Live.' More precisely, he really wanted to Lloyd it up, doling out hideous Lloyd Christmas-styled bowl cuts to the good people of Hollywood Blvd. How could this possibly go wrong?

You'd think that after three 'Hunger Games' movies, star Josh Hutcherson would have tapped into new levels of athleticism and competitive achievement. You'd be wrong. The actor hit 'The Tonight Show' last night to talk about the latest entry in the blockbuster film franchise, and it really only did some natural that he and host Jimmy Fallon would engage in some good-natured gamesmanship.
