Ethan Hawke stopped by Tuesday's "The Tonight Show" where he and host Jimmy Fallon did their best Bob Dylan impressions ... while singing lullabies.
While Fallon's known for his spot-on Dylan parodies, the "Boyhood" star doesn't sound half-bad either doing his own Dylan impression -- check out the cute clip above!
Hawke's definitely had some practice in the lullaby department, too: The actor has four children of his own, Clementine, 6, Indiana, 3, Maya, 16, and Levon, 12.
Fallon likewise has a baby girl, 20-month-old Winnie, who he said loves to stay up to watch the show. "If my daughter's awake right now, Winnie please got to sleep," the comedian told the camera before showing off his singing chops.
Ethan's impression of Dylan singing "Rock-a-Bye Baby," was pretty on-point, while Fallon's "Twinkle Twinkle" was sure to catch the attention of his baby girl.
