Jimmy Fallon

Are you ready to see Jimmy Fallon and Paul Rudd lay it all on the line to become the winner of this epic Lip Sync Battle?

If you have a tendency to overuse hashtags/are on Instagram or Twitter (same difference), you should check out this video from Justin Timberlake and Jimmy Fallon that addresses a very real problem.

Last night, 'Hello Ladies' star Stephen Merchant, Joseph Gordon-Levitt and Jimmy Fallon squared off in a lip sync contest, and things quickly got out of hand.

Jimmy Fallon is so bad. 'Breaking Bad,' that is.

In the same vein as that incredibly magical rendition of 'All I Want for Christmas Is You,' Jimmy Fallon, The Roots and a bunch of grade school instruments are once again making awesome music. This time it's a cover of Robin Thicke's nonstop hit 'Blurred Lines.'

Yesterday was Harry Potter's birthday. (We are *so* embarrassed that we forgot.) To celebrate, 'This is the End' star Simon Pegg got dressed up as Ron Weasley and showed up on Jimmy Fallon's show to wish him a happy birthday.

We're going to go ahead and assume you liked 'Full House' as a child, because every time we tell somebody that we didn't like 'Full House' as a child, we get weird sideways glances and also we have no friends left. Since you are clearly a huge 'Full House' fan, here's a video that's probably of interest to you -- Uncle Jesse (aka John Stamos) and his band The Rippers reunited on 'Late Night With J

It's not often that Michael Jordan does late night, and even less often that he makes an unscheduled appearance. Jimmy Fallon handles the shock of suddenly getting to meet a sports legend like the consummate professional that he is.

Good ol' Black Thought. Not only is he an amazingly talented member of The Roots and Jimmy Fallon's house band, but he's also willing to admit on national television that he's a "game freak." And then willing to do rap to the theme from Super Mario Brothers.

Well, you don't see this every day. Unless you come back every day and watch this video again. But let's not get caught up in particulars. Let's just watch Jimmy Fallon's very successful mashup of Brian Williams clips that makes him rap the lyrics to 'Nuthin' But a G Thang' by Dr...

If you're at all a fan of 'Late Night with Jimmy Fallon' then you are well aware of the heavily anticipated 'Game of Desks' digital original. The video aired this past Friday, and as you'd imagine, it did not disappoint.

Sit back and get ready for some of the best lip syncing you've ever encountered. No, not from Bieber or Miley Cyrus, but from a TV star and a soon-to-be late night legend. Yep, it's a lip sync-off!

It's official -- Jimmy Fallon is taking 'The Tonight Show' host spot beginning next February  And while he's surely elated as ever, we were curious as to what the last 'Tonight Show' host had to say. No, not Jay Leno. Conan O'Brien.

Adding another covered tune to his list of many, 'Late Night' host Jimmy Fallon decided to perform a duet with last night's guest Selenz Gomez. Their choice? The beloved 'Mario Kart Love Song.'

It's official, Justin Timberlake is one of the coolest guys in the world. To celebrate the upcoming release of Timberlake's third studio album 'The 20/20 Experience,' the crew at 'Late Night with Jimmy Fallon' is having a week of shows featuring the singer/dancer/actor...
