Black Simon And Garfunkel Sing 'All I Want For Christmas Is You' On Fallon (VIDEO)

Just in time for the holidays, Jimmy Fallon brought The Roots' Questlove and Captain Kirk Douglas back on Tuesday as "Black Simon And Garfunkel" for another hilarious cover.

This time, instead of showing how Simon & Garfunkel would do LMFAO's "Party Rock Anthem," the duo covered something a little more season-appropriate: Mariah Carey's "All I Want For Christmas Is You."

After hearing Questlove do his best Mariah impersonation, we have to say we're curious to know what a full-on Roots cover of the most overplayed Christmas pop song would sound like. Wouldn't that be something?
