Dave Grohl Joins Jimmy Fallon for a Hilarious Episode of 'The Tonight Show'

Rock and roll legend Dave Grohl hit the stage in New York for a special gig. The Foo Fighters founder brought his comedy talents to 30 Rockefeller Plaza as he hosted The Tonight Show, and some were shocked to learn just how funny this rockstar is.

Grohl began by joining Fallon in front of the live audience for the evening monologue, and the two talents laughed their way through the jokes. Jimmy hilariously promised Dave that "If things go well here, this could be the big break [he's] been waiting for." The humor was not lost on the 11-time Grammy Winner, who quipped back that "[Hosting] is definitely one of the coolest things that I've done... Today." The co-hosts then rolled into their list of news highlights and punch lines.

Highlights included a hysterical suggestion for the hand sanitizer backstock, which has grown as the pandemic has winded down. "You know the best hope that Purell has to unload their product at this point is turning it into Purell Hard Seltzer," Grohl joked. Fallon quickly responded with, "Yeah, I'd drink that!" The pair also touched on some entertainment news as it was recently announced that Timothée Chalamet was cast to play Willy Wonka in the highly anticipated Warner Brothers production. As Fallon put it, Chalamet had "officially made the jump from Little Women to Little Wonka." The co-hosts could barely contain their laughter.

Another memorable moment from this episode was a segment called "Off Songs, Song Off with Dave Grohl." The pair brought the house down with this hilarious musical game. The challenge required them to guess what song The Tonight Show's in-house band, The Roots, was playing. The twist? The music group performed each track in a totally different genre. Timeless titles, including Heart of Glass by Blondie and Back in Black by AC/DC, were some of the many puzzling remixes.

The Roots' performances stumped Fallon and Grohl as they called out their hysterical guesses. The final round resulted in major laughs, as Dave couldn't identify one of his own tracks! "I don't know my song," the former Nirvana drummer joked. Check out more highlights from the funny pals for yourself in the clip above. Safe to say, Jimmy and Dave went down in co-host history with their performance on The Tonight Show. Be sure to check back with us for more comedy news.
