A new “children’s book for adults” called Go the Fuck to Sleep by Adam Mansbach has taken the internet by storm and in the process has catapulted itself to the top of Amazon’s best-sellers list — a whole month before it’s even due for release.

How did this happen exactly? Well, blame book piracy as many people have somehow found themselves with a PDF copy of the book and found it so hilarious that they just couldn’t help but pre-order an actual copy through Amazon.

I’ve seen the PDF book and it’s very funny. If you somehow find yourself with a copy, maybe you’ll be enticed to order the actual book and read to your spouse or loved one. Or maybe your child.
