It's Friday, dammit, and you know what that means.

That's right: It's time to drop every single thing and watch Robin Thicke, Jimmy Fallon and The Roots perform a whimsically nostalgic cover of "Blurred Lines" with as many classic classroom instruments (and bananas) as they could find.

If this sounds familiar, it's because Fallon & co. have done this at least twice before: Once with Carly Rae Jepsen, and again with Mariah Carey.

And guess what? They've done it again.
