Not so much a story as a series of vignettes detailing urine throughout history. There is a lot of knowledge in here that you haven't learned, or may have forgotten. Generally amusing without stooping to scatological humor.
The only real complaint about the book is the font size. The version of the book I have is about the size of a standard Kindle, but the text is devilishly small. If it wasn't for font size alone, I would have finished this book the week I got it instead of setting it aside for a while.
