Last night's 'Tonight Show' was just chock-full of surprises!

Jimmy Fallon has never been a teenage girl. Taylor Swift, however, has. Still, the veracity that Fallon brings to his performance as a teen in his fake-talk-show-within-a-talk-show, 'Ew!,' is pretty striking -- he somehow seems like more of a teenage girl than his guest, who was a teenage girl mere years ago. It's madness!

A choked-up Jimmy Fallon took to 'The Tonight Show' last night to pay tribute to the recently passed Robin Williams, a highly emotional affair that should help squeeze one last round of tears out of Williams' many shocked and saddened fans.

Poor Nick Cannon. Perhaps the 'Tonight Show' guest realized he'd want to hide after last night's show, thus deciding to kit himself out in a camouflage suit before he even hit the stage. Cannon was paired up with Megan Fox during the latest round of Jimmy Fallon-approved Pictionary, and the pair turned in a ... well, it was a pretty dismal performance.

Jimmy Fallon from the Tonight Show never fails to make me laugh, and when you add funny lady Whoopi Goldberg to the equation, you get comedy gold!

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.

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.

Well, this one pretty much sells itself. Jimmy Fallon unveiled a Father's Day-targeted take on his ever-popular "Evolution of Dance" on last night's 'Tonight Show,' and this one just hit it right out of the park.

Imagine a mythical land -- a small town, really -- where there's only room for just one inhabitant to sport some tight, tight pants. How would people challenge each other for tight-pants supremacy? Last night on 'The Tonight Show,' just such a showdown hit the screen, when host Jimmy Fallon deluded himself into thinking his tight pants could somehow prove to be better, badder and tighter than Jennifer Lopez's tight pants.
