Watch: Ethan Hawke and Jimmy Fallon Sing Lullabies as Bob Dylan

Ethan Hawke

Ethan Hawke arrives on the red carpet for the 86th Academy Awards on March 2nd, 2014 in Hollywood, California.

How does it feel to have trouble sleeping? Perhaps Bob Dylan can help.

Ethan Hawke was a guest on Tuesday's Tonight Show, where he explained to Jimmy Fallon that he had devised a foolproof plan for getting his children to nod off.

"You ever play the guitar for them?" the Boyhood star asked fellow father Fallon. "Did you ever try impersonating Bob Dylan?"

At that, both of them magically pulled out guitars and took part in a Dylan-off, as they performed impressions of the folk-rock hero doing lullabies like "Twinkle, Twinkle, Little Star."

To see The Roots back them up for their final number, watch the video below.
