Go the F**k to Sleep; co-written by Ricardo Cortes is a crude attempt at humor. It is sort of a poem about the trials and tribulations of trying to get a young child to go to bed. The illustrations by Ricardo Cortes are okay. I’m not sure what made this book so popular other than it is so short. You can read it in five minutes. It seems like a gag gift. I’m guessing the Audio version is better as Samuel L. Jackson reads it.
