Jimmy Fallon

Somehow, 'Foxcatcher' star Channing Tatum is the very first male guest to participate in a rousing round of Jimmy Fallon's 'Box of Lies' on 'The Tonight Show.' Fallon's results have been mixed -- the guy isn't very good at lying, especially when a giggly celebrity makes googley eyes at him in an attempt to throw him off his game -- but he has been getting better in recent weeks.

'Ew!' is for sure one of Jimmy Fallon's most entertaining bits. Even with all the game-heavy fair permeating his 'Tonight Show,' one can never really get tired of seeing Fallon and the evening's celebrity guests pulling off some sassy-teenage-girl realness. However, this time around, Fallon took things up a notch by transforming the popular sketch series into a music video with will.i.am.

Sofia Vergara knew exactly what she was doing the second she took the 'Tonight Show' stage last night. The 'Modern Family' star was hellbent on one thing: playing one of host Jimmy Fallon's favorite games (and we know how much Fallon loves games) and using it to totally turn the tables on him. You like Lip Flip, huh, Jimmy? Right? You don't like it as much as Sofia does.

Last night (Sept. 18), Robin Williams' close friend Billy Crystal shared fond memories of the late star with Jimmy Fallon.

Jimmy Fallon has already proven time and again his skills at impressions, especially of famous singers.  Little did we know, he's not the only one with this skill set.  Last night on the show, Adam Levine was a guest, and faced off head to head with Jimmy on the best musical impressions.  Admittedly, we were blown away.

The '50 Shades of Grey' trailer is alternately steamy and scary, but late-night host Jimmy Fallon wasn't content to show it to his house band, the one and only Roots, as is. Nope, that thing needed to be modified just a touch, to really make sure that the band was paying the proper attention to their trailer-watching assignment. So the 'Tonight Show' host did what anyone would do -- he inserted a scary scream face into the middle of the trailer. Obvious, right?

If you ever wanted to play an epic round of Catchphrase with Jimmy Fallon and James Franco, you're in luck: The two basically did just that in a new 'Tonight Show' game called '5-Second Summaries'.
