Robin Thicke stopped by the Late Night With Jimmy Fallon show on Thursday (August 1) and lent his falsetto voice to a fun version of his hit song "Blurred Lines." Also included: The Roots, show host Jimmy Fallon and a whole lot of kid's musical instruments.

Flanked by Fallon (on wood block) and The Roots (on xylophone, cowbell, maracas, guitar, some form of banana shaker and, of course, the "Hey, Hey, Hey" refrain), Thicke didn't miss a beat despite the intimate (read: cramped) dressing room space.

It's just a fun, silly version of "Blurred Lines" -- a song that has been criticized over its provocative lyrics and an NSFW unrated version that was banned from YouTube.

Of course, this isn't the first time Fallon has invited a musical guest to perform a cuter version of their song live on the show. Last year, Carly Rae Jepsen did the same thing following the breakout success of her single, "Call Me Maybe."
