Watch Ethan Hawke, Jimmy Fallon channel their inner Bob Dylan to sing a few lullabies

You know what really helps put a child to sleep? According to Ethan Hawke, all it takes is a guitar, a lullaby, and a Bob Dylan impression—and that kid will be out like a light.

Hawke joined Jimmy Fallon on Tuesday’s Tonight Show to share his lullaby wisdom. Luckily, both stars had their guitars ready to give the audience a taste of how parents should best prepare for bedtime. The two are pretty adorable as they put a new spin on classics like “Rockabye Baby,” “Twinkle Twinkle Little Star,” and “Hush, Little Baby.” Fallon even gives a special shoutout to his little one, Winnie.
