Watch Robin Thicke perform "Blurred Lines" with Jimmy Fallon and The Roots!

In case you hadn't noticed, Jimmy Fallon kinda loves an opportunity to jump on the latest pop music trend. And when we say "jump," we actually mean "perform pop songs using children's classroom instruments." (See: Jimmy's "classroom" performances with Carly Rae Jepsen, Mariah Carey, etc.) And now, to add to his list of classroom performances, Jimmy has teamed up with Mr. Falsetto, aka Robin Thicke, for an acoustic rendition of "Blurred Lines"! Plus a few (read: all) members of The Roots! Three words: Sign. Us. Up. (And take us to Toys R Us. Please? IT'S BEEN SO LONG.)

Watch Robin Thicke Perform "Blurred Lines" with Jimmy Fallon and The Roots after the jump.

Using things like little colorful keyboards, maracas, kazoos, recorders, cowbells, and A BANANA SHAKER (just watch, you'll see), Robin and his troupe of "Late Night" performers blew through a beyond-charming acoustic R&B rendition of "Blurred Lines." And just in case you were wondering, "Hey (hey hey), who covered T.I.'s rap break?" Oh, not to worry -- The Roots took care of that. Not to create any undue competition, or anything, but top THAT, Vampire Weekend!
