Stephen Colbert to Sing Rebecca Black's 'Friday' on Jimmy Fallon's Show for Charity (Video)
Want to hear Stephen Colbert sing Rebecca Black's "Friday"? Better open your wallet.
The Colbert Report host recently auctioned off a painting of himself for $26,000 to benefit charity and subsequently announced on his show that Jimmy Fallon, his "best friend of six friends," was planning to match the donation.
The only problem? Fallon hadn't actually said that.
On Tuesday's Late Night With Jimmy Fallon, Colbert made a surprise appearance to urge Fallon to donate to DonorsChooose.org, which helps classrooms in need.
Ultimately, Fallon got back at Colbert with a "promise" of his own.
"If we can raise $26,000 by this Friday, I will promise that my BFF for six months, Stephen Colbert, will come on this show and sing Rebecca Black's 'Friday' with the Roots, and that is a promise that I am making from him to you," Fallon told viewers.
To donate, visit DonorsChoose.org, which noted on its website that "this is not an April Fool's joke."
