'Blurred Lines' is the biggest song in the world right now, and the only thing that can make it bigger is The Roots playing it on kids toy instruments while Robin Thicke and Jimmy Fallon sing along.

This has become a staple of Fallon's show, and bits like this are exactly why people are ready to crown him the next king of late night.

Black Thought jumps in where T.I.'s verse was, and maybe it's the overall vibe of the performance  . . . but I think his verse is better than the original!
