By now, it seems that every celebrity under the sun has taken the ALS Ice Bucket Challenge -- even your favorite Marvel stars -- but there is still a handful of big names who have yet to take the plunge. One obvious choice? Lindsay Lohan, who seems to have so far slipped through the cracks. Well, at least until one random fan challenged her to the task and then employed Jimmy Fallon to make it happen on 'The Tonight Show.' Oh, you're done for now, Lohan.

James Franco has never been one to shy away from selfies, even the kind he probably shouldn't be taking and putting on the internet. Over the years, he's developed a well-oiled system for making them work, especially the ones he takes with his eager fanbase.

Supermodel Miranda Kerr has never played flip cup -- she is, after all, an Australian, and there seems to be some debate that flip cup is an inherently American game -- but that doesn't mean that the beauty doesn't have skills. In fact, she's really good, and she definitely put 'Tonight Show' host Jimmy Fallon on the spot last night when the duo took to the Official Tonight Show Flip Cup Table (not a thing, but let's pretend it is) for a round of the drinking game.

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.'

'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.

Channing Tatum ('22 Jump Street') is challenged to an arm wrestling match by Jimmy Fallon on 'The Tonight Show.'

Jennifer Lawrence stopped by 'The Tonight Show Starring Jimmy Fallon' last night (May 15), and as you might expect, putting the hilarious actress and the outrageously funny host in a room together produced some pretty amazing results.

We've seen Jimmy Fallon bring guests on 'The Tonight Show' to do everything from lip sync battles to Broadway covers of rap songs and they have all been amazingly fun to watch. So when he brought out Kevin Spacey to do a barbershop quartet rendition of Jason Derulo's 'Talk Dirty,' we weren't surprised that actually sounded incredible.

Move over, J. Law! America has a new Girl Crush and her name is Shailene Woodley. The 'Divergent' star looked fine in a leather LBD on 'The Tonight Show Starring Jimmy Fallon' (March 12), although we were thrown by the penis-shaped herbal remedies she brought!

Jimmy Fallon brought a popular 'Late Night' segment over to 'The Tonight Show' with him. The first challenger in the comedian's famous lip sync battle? Paul Rudd!

Usher, wearing a furry hat that rivaled what Pharrell Williams wore to the Grammys, teamed up with 'Tonight Show' host Jimmy Fallon (Feb. 24) to play a friendly game of 'Catchphrase' with actress Reese Witherspoon (and her lovely asymmetrical bob) and Olympian Mikaela Shiffrin.
