Stephen Colbert, Jimmy Fallon Sing Rebecca Black's 'Friday' (Video)
Earlier this week, Jimmy Fallon issued a challenge. If viewers donated $26,000 to a worthy charity by Friday, his "Best Friend for Six Months" Stephen Colbert would appear on Late Night With Jimmy Fallon and perform Rebecca Black's seminal hit, "Friday."
Sure enough, the public didn't disappoint.
Colbert kept true to his word and performed the song with Fallon, American Idol season 5 winner Taylor Hicks, the Knicks City Dancers and The Roots. "The whole thing was genius and absurd," Hicks tells THR. "Not to mention fun, fun, fun, fun!"
