Fox 2000 has picked up rights to the humorous bedtime book for adults Go the F**k to Sleep, from Adam Mansbach.

In the book, Adam Mansbach captures the endless bedtime routine that all parents endure. Despite its crass title (and refrain), it's actually a tender, tongue-in-cheek peek inside a father's journey of putting his child down for the night.

The studio has not set a director or writer on the project.
