Dave Chappelle stopped by The Tonight Show last night, after making an appearance on Late Show earlier this week, and spoke about the first time he met The Roots, as well as the first—amazing—time he met Kanye West.

On tonight's The Tonight Show with Jimmy Fallon, disgraced New Jersey governor Chris Christie danced like no one was watching in the "Evolution of Dad Dancing" skit. The "joke" is that Chris Christie dances like a buffoon that makes you want to scrub your eyes with bleach, and it is also "true." Way to get in front of the ridicule this time, Chris.

Late night TV is apparently only big enough for one person in tight pants, so Jimmy Fallon challenged Jennifer Lopez and her heavily-insured booty to a pants-on dance-off. Two pairs of tight pants enter, one pair of tight pants leaves.

Professional gigolo and miracle of modern science Channing Tatum appeared on the Tonight Show Friday night, and, like many pretenders before him, Jimmy Fallon wanted to challenge Tatum to an arm-wrestling match.

Two things we learn about Tom Cruise from this game of "Face Breakers," where he and Jimmy Fallon throw footballs at glass frames with their faces etched onto them: Tom Cruise is pretty good at throwing footballs; Tom Cruise takes himself very seriously while throwing footballs. This is how you win games on late night talk shows.

Yesterday, just hours after the footage of Jonah Hill calling a paparazzo a "faggot" was posted by TMZ, the actor shared his regrets regarding the slur on Howard Stern's Sirius show. On last night's Tonight Show with Jimmy Fallon, Hill reiterated his remorse while accepting full accountability for not just his words but their weight beyond his intention:

Lipsync-offs are great and all, but when Jimmy Fallon has a sharp improviser like Ricky Gervais on his show, there's only one recurring segment that makes sense: Word Sneak.

On last night's Tonight Show, doppelgängers Will Ferrell and Red Hot Chili Peppers drummer Chad Smith finally settled their long-standing feud with a much anticipated drum-off. I won't give away the ending, but there was cowbell and a surprise musical guest.

Jimmy Fallon, in his eternal quest to push the celebrity lip-sync-off format to its limits, invented a terrifying new challenge just for Brooklyn Nine-Nine actor and ex-NFLer Terry Crews: The celebrity nip-sync.

Lincoln is an average guy—and above-average lipsyncer—from Canada, whose dream is to appear on the Tonight Show and take on Jimmy Fallon in a lips sync duel.

Jennifer Lawrence was not so happy with Jimmy Fallon after he ditched her in front of JLo at a recent party.

Continuing her streak of making straight-laced late night TV hosts blush, Amy Schumer was on Late Night With Jimmy Fallon last night, where the two played a game of "Truth or Truth," which is the network TV-approved version of "Truth or Dare."

The object of Jimmy Fallon's "Word Sneak" game is to work some preassigned random words into a conversation as seamlessly as possible. But for Bryan Cranston to do that, he'd have to know what a badonkadonk is. Which he clearly does not.

On Friday's Tonight Show, Kevin Spacey sang Jason Derulo's "Talk Dirty" with Jimmy Fallon's barbershop quartet, The Ragtime Gals. They did a great job.

This is the Tonight Show in 2014, in which we learn that Annie Hall either doesn't know or just doesn't care how beer pong works.

Jimmy Fallon challenged Emma Stone to a lipsync-off on the Tonight Show Monday, and while Fallon had the home field advantage, the Amazing Spider-Man 2 actress delivered on style and degree of difficulty. And Ludacris.

Apparently actual late nights with Jimmy Fallon involve narrowly escaping bar fights and buying shots for everyone around him.

Earlier this year, Anne Hathaway said she had decided that people needed a break from her. Well, break's over. The Les Mis Oscar winner and diary-keeping princess who everyone loves to hate teamed up with Jimmy Fallon to Broadway-ify some hip-hop tracks.

Samuel L. M.F. Jackson dropped by The Tonight Show to put into slam poetry the emotions we all felt in the '90s, when Boy fatefully met World. And also, Topanga. Topanga. Topanga. Topanga.

While the rest of us click on Arnold Schwarzenegger soundboards to hear classic Ahnoldisms like, "Who is your daddy?" and "It's not a tumor," Jimmy Fallon just writes the man himself into his sketches. And last night, Fallon really wanted to hear "Get to the choppa!"
