Jimmy Fallon returned to host Saturday Night Live for the first time since 2013 and the versatile star kicked off the night with a massive musical monologue.
After appearing as Ivanka Trump's husband, Jared Kushner, in a hilarious and (mostly) silent role in the cold open, Fallon took to the Studio 8H stage to open up SNL's first-ever live-on-both-coasts episode with an epic dance number involving dozens of back-up dancers.
"Tonight is bigger than just a show," Fallon said, as David Bowie's "Let's Dance" began to swell. "It's a party!"
Lip syncing like a pro, Fallon walked off stage and was followed by a studio audience (filled with professional back-up dancers) as they danced through the halls of the studio.
Joined by the entire cast of SNL singing and dancing along with him, Fallon also shared a fun lip sync duet with music guest Harry Styles, and their adorable comic chemistry was palpable.
Check out a few of Fallon's best sketches of the night below:
"Donald Trump Cold Open"
"Take Me Back"
"Celebrity Family Feud: Time Travel Edition"
"Sully & Denise"
Early Saturday morning, the former SNL cast member took to Instagram to commemorate his history with the long-running sketch comedy series, sharing a mirror selfie from his dressing room, with a cheeseburger and a shake on the table in front of him.
"In 1998 hours before I auditioned for Saturday Night Live - I got a cheeseburger and a banana health shake (ice cream, banana and wheat germ - really healthy) from Ellen's Stardust to go. I have it once a year for good luck. They now have my name on the menu," he wrote. "I'm so happy to be home and I hope you enjoy the show. #FallonStylesSNL"
