Last night, Robin Thicke joined Jimmy Fallon as the late night host did another one of his "music room" bits, in which he and The Roots cover a song using instruments you might find in an elementary school classroom. As you'll hear, "Blurred Lines" sounds fantastic with keyboard beats, xyophone, spoons and a kazoo. Questlove dancing with a clacker is delightful. And instead of T.I. talking about "tearing" an ass in two, Black Thought came up with some romantic rhymes: "The best girlfriend I ever had is you… So I put a ring on it and I married you… You're gonna have these other girls getting mad at you, because you've got brains, looks, and attitude." Sweet.

The line-up is as follows:

Jimmy Fallon - wood block, Casio keyboard
Robin Thicke - spoons
Questlove - wooden clacker
Mark Kelley - kazoo
Kamal Gray - xylophone
James Poyser - melodica
Captain Kirk - ukulele
Tuba Gooding Jr. - recorder, banana shaker
Frank Knuckles - cowbell
Black Thought — maraca

(Cue the MORE COWBELL!)
