Jimmy Fallon

'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.'

Last night (July 8), Oscar-winning actress Halle Berry stopped by 'The Tonight Show Starring Jimmy Fallon' -- and formed a hamster wheel with the host!

Jimmy Fallon's love for turning basic drinking games into outsized (often, quite literally) versions of themselves is well documented, but the 'Tonight Show' host just might have reached the apex of his drinking game adoration when he challenged Pitbull (Mr. Worldwide, please) to a round of Giant Duff Beer Pong. Wait, why Duff? Because Fallon and his show have been camped out at Universal Studios in Orlando all week, and yes, this game is all about Duff Beer, the favorite fictional beer of 'The Simpsons.'

Attention, 'Harry Potter' fans: You have one equal-parts Potterhead and rap enthusiast to thank for the incredible 'Harry Potter' rap you're about to enjoy.

'The Tonight Show' is down in Orlando for the week, and although the 'Harry Potter' theme park they overtook is packed with families, it's really for the kids, because it doesn't seem as if any of the parents in attendance have ever even picked up a book. Need proof? Jimmy Fallon sent out a writer to quiz some park-goers (no kids!) about some basic 'Potter' trivia, and the results were kind of dismal.

'Tonight Show' host Jimmy Fallon and screechy-voiced comedian Kevin Hart both hate roller coasters, but the guys decided to face their fears together (aww) by taking a special spin on Universal Studio Orlando's massive Hollywood Rip Ride Rockit roller coaster.

'The Tonight Show' is down in Orlando, Florida, this week, camped out at the Universal Studios backlot for some road-tripping fun, and all the better to serve up some exciting sneak peeks at the theme park's newly expanded Wizarding World of Harry Potter. Jimmy Fallon decided to really get into the spirit of things, dragging his faithful announcer Steve Higgins over to Diagon Alley to pick out some shiny new wizarding wands from master wand shop Ollivanders.

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.'

Just a few weeks after they shimmied together in the magic that was 'Tight Pants,' Jennifer Lopez is once again dancing with Jimmy Fallon -- and let's face it: she kind of owed him after that whole dance diss debacle.

Dave Chappelle tells a story to Jimmy Fallon on 'The Tonight Show' about meeting a young, confident Kanye West back in 2004.
