Robin Thicke's 'Blurred Lines' is one of the year's sexiest music videos. Now, the crooner and the good folks at 'Late Night with Jimmy Fallon' have remixed the song to make the tune more family-friendly.

Robin and the Roots get out their Fisher Price instruments, including a rainbow xylophone, to give the song a kid-geared sound.

"The best girlfriend I ever had is you ... So I put a ring on it and I married you," Questlove raps while waving a maraca.

For some reason, they keep the racy hook intact.

Aww. Isn't that precious?
