The Tonight Show Starring Jimmy Fallon

Matthew McConaughey will be Fallon's first guest on October 2, the talk show host said—or rather, sang. 

The "vampire" singer delivered a pitch-perfect performance of her tender breakup song on The Tonight Show Starring Jimmy Fallon in 2021. 

The Saturday Night Live alum also showcased her jaw-dropping imitation of country icon (and Cyrus's godmother) Dolly Parton.

SNL friends and Bravo's Andy Cohen shared well wishes under a throwback post that shouted out The Tonight Show Host's mom and dad. 

The singer also lent her incredible voice to autumn-themed versions of Alanis Morissette's "You Oughta Know" and The Eurythmics' "Sweet Dreams (Are Made of These)." 

Drew visited "Ew!" and Paul Rudd rocked a teenie weenie beanie in two of the most popular Tonight Show sketches from its most recent season.

The Tonight Show Host called the karaoke moment "one of those nights I will never forget"—and filmed a hilarious TikTok with the Jonas Brothers backstage. 

From the all-out hilarious to the hilariously awkward, these have us laughing every time we rewatch. 

Taylor Swift and Jenna Ortega also flexed their acting skills to beat Fallon at his own game.

Kate Beckinsale and Kim Kardashian also bravely stuck their hands in the "Can You Feel It?" box.
