This is not a description but rather a disclaimer: this is an exceptionally hilarious book. It is also, as A.J. Jacobs points out, "very dirty."
It's not any dirtier than most of the adult dramas currently streaming on Netflix, but for some reason it seems that way whenever people discuss their experience of reading it. Perhaps it's the tactile nature of the experience: holding a book is practically a fetish these days. BUT YOU ARE DULY NOTIFIED: those readers of more delicate sensibilities or tender age should refrain from this title.
