Robin Thicke joined Jimmy Fallon and The Roots on Thursday night to perform a version of the singer’s summer smash, “Blurred Lines”, with children’s instruments.

Thicke played spoons, with Fallon on a wood block and Casio keyboard, while The Roots used everything from a ukulele to maraca, xylophone, melodica, kazoo and more.

“Blurred Lines” is the song of the summer of 2013, without question, as it sits atop the Billboard Hot 100 singles chart for an 8th week.
