This is the best video you'll see all day, trust us.

"Late Night with Jimmy Fallon" has been a goldmine of great viral moments lately -- and last night, Jimmy did it again with a killer performance of "Blurred Lines."

Just when you thought you've heard this song way too many times, Robin Thicke, Fallon and The Roots found a way to make it sound new again.

By performing it with instruments you'd find in an elementary school classroom!

This isn't the first time the late night host has performed some stripped-down versions of big hits. In the past, he's performed with Carly Rae Jepsen, Christina Aguilera and even Mariah Carey.

Keep 'em coming, Jimmy!
