Jimmy Fallon has created a monster with his Lip Sync Battles, and Lena Dunham's appearance on Friday was another awesome example of how great it can be.

June 23rd. That's when the world get their first listen to Kacey Musgraves sophomore album, "Pageant Material." Ahead of the release date Musgraves will be stopping by not one, but two NBC late night shows.

Madonna: Legendary icon. Material Girl. Queen of Pop. Stand-up comedian?

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.

Christina Aguilera joins Jimmy Fallon on the Tonight Show last night to promote NBC's 'The Voice,' where voice became the star.

Jimmy Fallon has followed through on his promise to reunite the cast members of the 90's Saturday morning classic, 'Saved By the Bell.'

It's Water War! Jimmy Fallon's most bizarre and icy cold game yet! A game of chance, and um, hydration, Water War pits the 'Tonight Show' host against an especially down-for-whatever guest (after all, what sort of person would be okay with having water poured all over them on national television? a cool one, that's who!) in a battle to see who can get more soaking, sopping wet. That's the aim of the game, right? No? Then 'Blackhat' star Chris Hemsworth lost? What kind of world is this?!

No, you have not gone crazy--Oprah Winfrey and Jimmy Fallon never starred in a soap opera, certainly not one together--but let's not let that small factoid get in the way of a good (if wholly imaginary and also extremely weird) sketch.

Is there anything Matthew McConaughey can't do? Or, more precisely, is there anything that he can't do excellently? Turns out, the Oscar winner just might have a weak spot, and although it's not a big one, it's one that 'Tonight Show' host Jimmy Fallon gleefully exploited for his own edification on last night's show.

Harry Potter fans your love for Daniel Radcliffe is about to taken to the next level when you watch him rap on the Tonight Show with Jimmy Fallon.
