Jimmy Fallon

Jimmy Fallon's barbershop quartet were performing on The Tonight Show, along with a little help from Actor Steve Carell! Watch as they sing Marvin Gaye's Sexual Healing.

It turns out that Ben Affleck's kids are so obsessed with 'Frozen' that they want to watch it as much as possible -- and want him to sing along!

Who knew that Adam Levine of Maroon 5 could bring out his inner Frank Sinatra or Michael Jackson?

You gotta hand it to Taylor Swift, she can definitely act too! (and keep herself from laughing better than Jimmy Fallon)

Undoubtedly influenced by the comedic genius of Robin Williams, Jimmy Fallon put together a movie tribute for the actor, who committed suicide this week at the age of 63.

Morgan Freeman has one of the most famous and recognizable celebrity voices. Whether he's acting or narrating, you always know it's Morgan. On a recent visit to The Tonight Show with Jimmy Fallon, Jimmy convinced Freeman to let us hear his voice...chipmunks style!

'SNL' alum Dana Carvey swung by 'The Tonight Show' the other night, and host Jimmy Fallon couldn't resist asking the funnyman to do some impressions -- with a twist, of course. Using not one, but two "Wheel of Impression" spinners, Fallon determined who Carvey would imitate and what he would talk about. Too bad those things seemed weighted towards Al Pacino. Now that's weird, wild stuff.

'Live' co-host Kelly Ripa stopped by 'The Tonight Show' with Jimmy Fallon last night (July 9) and the two talk show hosts faced off in a hilarious battle of pop culture knowledge in a new segment titled 'Pop Quiz.'

Remember when NBC News anchor Brian Williams "rapped" Snoop Dogg's 'Gin and Juice' and Sugarhill Gang's 'Rapper's Delight'? Well, the respected anchor is spittin' those rhymes yet again, thanks to Jimmy Fallon and 'The Tonight Show' crew who carefully edited clips of Williams to make it appear like he's rapping Sir Mix-A-Lot's 'Baby Got Back.'

I hate roller coasters.  I used to be really scared of the rides because I'm scared of heights.  Then my buddy peer pressured me into riding the kingda ka at Great Adventure, which led to the worst experience of my life.  So, I can only imagine what Comedian Kevin Hart went through.

In honor of Father's Day, Governor Chris Christie and Jimmy Fallon showed us 'The Evolution of Dad Dancing'.  I never thought I would be watching Chris Christie do 'The Belt Grabber' or the 'The ‘Passionate Elliptical' dance!

Whoa, these are some talented mammaries! Jimmy Fallon may have mastered the art of lip synching, but he took his talents to a whole other level on The Tonight Show when he and Brooklyn Nine Nine star Terry Crews tacking nip synching.
