"This one's for the children!" There's something oddly soothing about watching Jimmy Fallon play flip cup with big stars on his 'Tonight Show.' The college drinking game suddenly seems classy, refined, even a little zen, especially when someone like 'The Face of Love' star Annette Bening shows up to chug beer and flip Solo cups alongside the host.

Tina Fey was Jimmy Fallon's Guest On Late Night this week, and it got crazy! They flipped lips!

Last night (March 3), Jimmy Fallon brought another of his well-known segments to 'The Tonight Show.' The comedian and his house band, the Roots, gathered together to perform 'Let It Go' with Idina Menzel.

Awwww, yeah! Justin Timberlake and Jimmy Fallon celebrated 'The History of Rap' on JT's first visit to the new-look, Fallon-hosted 'The Tonight Show' on Feb 21.

British pop superstar "Harry Styles" was a couch guest on last night's episode (Feb. 18) of 'The Tonight Show' with Jimmy Fallon. Of course it wasn't the One Direction heartthrob. It was actress Kristen Wiig, a former 'SNL' castmate of Fallon's, nailing it with her Hazza impression.

It was on like Donkey Kong for Jimmy Fallon's first episode (Feb. 17) as host of the new 'Tonight Show.' He demonstrated the evolution of hip-hop dancing with a little help from rapper-turned-actor Will Smith.

Last night, Jimmy Fallon officially ushered in a new era of 'The Tonight Show' and, besides a move to New York City, already made the show his own. Can you imagine Jay Leno ever doing The Humpty Dance in a "The Evolution of Hip-Hop Dancing"?

Miley Cyrus appeared on 'Late Night With Jimmy Fallon' this week to promote 'Bangerz' and to show off her "gets it" personality. The singer performed an a cappella version of 'We Can't Stop' as the center square in a 'Brady Bunch'-style grid.

Even if you don't like football, everyone can get a laugh from anything that Justin Timberlake and Jimmy Fallon do together.

Justin Timberlake and Jimmy Fallon have brought us many great television moments together: their classic 'History of Rap' series, a barbershop-quartet version of 'Sexyback,' the talk-show host dubbing JT the "President of Pop" at last month's MTV VMAs. Well, get ready to add one more highlight to the list: 'The Evolution of End Zone Dancing'!

As if you didn't have enough reasons to love Ariana Grande, she also has a pretty good sense of humor behind those powerhouse pipes! The 'Sam + Cat' starlet and 'Yours Truly' singer joined Jimmy Fallon for a silly duet in which they belted out Broadway renditions of classic (and one newly classic) rap joints.

It's true the Roots just make everything better!  This is an amazing rendition of the song using nothing but kids instruments.
