Days after the tipsy talk show host stopped by Marie's Crisis, a legendary gay piano bar in Manhattan's West Village, "The Tonight Show" funnyman Jimmy Fallon took the Internet by storm this weekend.

At Marie's Crisis, Fallon belted "The Theme from Greatest American Hero (Believe It or Not)," led the crowd in singing the "Grease" jam "Summer Nights," stomp-clapped through Katy Perry's "Walking on Air" and crooned Billy Joel's "Piano Man," according to NewNowNext. This seemingly prepared him for one of his biggest lip sync battles.

According to the Huffington Post, Fallon invited fellow "Saturday Night Live" alum "Anchorman 2" star Will Ferrell and comic du jour Kevin Hart ("The Wedding Ringer") to the show.

Live from Phoenix, Arizona, for a special Super Bowl Sunday edition of "The Tonight Show," Ferrell and Hart joined the night's lineup to promote their upcoming prison comedy film, Etan Cohen's "Get Hard." As usual, laughs ensued when Fallon challenged the duo to a lip sync battle.

Ferrell, toting a Seahawks hoodie, began the festivities with Beyoncé's smash single "Drunk In Love," which Fallon joked that he can't "unforget" what he had just witnessed. The host then mimed Kelly Clarkson's "Since You Been Gone" to a roaring audience before an explosive finish and dropping his mic drop.

Following up, Kevin Hart gyrated toward the audience and serenaded Ferrell with John Legend's chart topping "All of Me." Although he dedicated the performance to his "rib," Eniko Parrish, a picture of Legend's model-blogger wife Chrissy Teigen flashed across the screen. Shortly after a second round was announced and Ferrell followed up with a favorite from 'Adele Nazeem,' "Let It Go" from Disney's "Frozen," and instantly won the battle.

It was not without difficulty. Performing "I Had the Time of My Life" from the cult '80s romantic comedy/drama "Dirty Dancing," Fallon was also joined by his "Fever Pitch" co-star Drew Barrymore as a surprise guest. Upon busting out the dance moves and launching Barrymore in the air, Fallon ripped a hole in his pants. Hart also promised to bring the house down with a rendition of Katy Perry's "Roar," and he did, inspiring a rousing clap along from the crowd.
