Jimmy, you did us proud.
The comedian kicked off his first Tonight Show Monday, marking, as Fallon himself said, "a moment in TV history."
But to Fallon fans, it was the same ol' Jimmy, making the audience feel right at home with another rousing rendition of "The Evolution of Dance." This time, Will Smith co-starred, reminding us all of hip hop dances of generations past.
The duo covered everything from the "Hey Ho" to the "Dougie" to twerking. And of course, hip hop can't be complete without "the Carlton" from the Fresh Prince of Bel Air.
Fallon's "evolution" skit was a fan favorite from Late Night, where the comedian previously paired with first lady Michelle Obama to demonstrate the "evolution of mom dancing" and with pal Justin Timberlake to showcase the "evolution of end zone dancing."
And while Smith may have been Fallon's first official guest, plenty of other guests stopped by the set to make good on old debts.
"To my buddy who said I’d never host the Tonight Show. You owe me $100," Fallon joked, prompting a parade of celebs, including old Saturday Night Live buddy Tina Fey, Stephen Colbert, Kim Kardashian and even Lady Gaga to hand over some cash.
U2 served as the night's musical guests, performing from the top of the Rockefeller Center.
And, no Tonight Show would be complete without a monologue. Fallon's was gracious and sweet, but that didn't stop him from taking a quick jab at former host of 22 years Jay Leno.
