'Tonight Show' host Jimmy Fallon often turns to his loyal fans to find and submit strange stuff, especially when it comes to his always-amusing 'Screengrabs' segment. Yet, crammed between those terrible stock photos and awkward weather forecast emoticons, this week's 'Screengrabs' segment packs a special punch.

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.

Will Ferrell is no stranger to rivalries, but although the star might be used to coming to blows with John C. Reilly on the big screen (remember 'Step Brothers' and 'Talladega Nights'? yeah, ya do), it seems like he's taking his act to the small screen with a new nemesis. On last night's 'Tonight Show,' a seriously revved up Ferrell hit host Jimmy Fallon's stage alongside Red Hot Chili Peppers drummer Chad Smith, who just so happens to look startlingly like Ferrell.

'Tonight Show' host Jimmy Fallon has been farming out plenty of his gags lately, asking his audience to send in various funny bits as they fit certain themes. Last night, he shared a batch of loyal fan-submitted screengrabs from both the internet and television -- a selection of some strange pictures, mismatched text, and a Captcha so bizarre that its hidden message popped up (tee hee) throughout

It's safe to say that Diane Keaton doesn't understand the mechanics of beer pong, or perhaps she does and just decided to troll 'Tonight Show' host Jimmy Fallon -- hard -- with a spin on one of his very favorite games.

Let it never be said that Jon Hamm doesn't like to have a good time. The 'Mad Men' star might be known for his hard-nosed role on the uber-dramatic AMC series, but he likes to stir up mirth in his off-time, from 'SNL' hosting and pop-in appearances to helping 'Tonight Show' host Jimmy Fallon with some gags for his show. In keeping with the latter, Fallon and Hamm took to the Top of the Rock (on to

Awww, Adam Sandler and Drew Barrymore reunited on 'The Tonight Show Starring Jimmy Fallon' last night (Feb. 26.)

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!

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.

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"?
