On Monday's "Tonight Show," the unthinkable happened: U2 had to postpone its in-house residency thanks to singer Bono sustaining an arm injury over the weekend. So what did Jimmy Fallon do with that particular lemon? He made lemonade!
It was a last-minute scramble, but having to fill in for a musical act is pretty much a piece of cake for Fallon, who stepped up to the mic and did what Bono couldn't: sing the band's 1988 hit "Desire," backed up by The Roots.
But Fallon wasn't done with U2 yet. He made sure they came up during his chat with Benedict Cumberbatch, who famously photo-bombed the band during the 2014 Oscars:
And while his other guest, Allison Williams, had no particular U2 connection, Fallon — who is is officially the hardest-working man in late night — happily took to the air as she showed him how she's been learning to fly for the upcoming "Peter Pan Live!"
"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET on NBC. "Peter Pan Live!" is set to air on NBC Dec. 4 at 8 p.m. ET.
