For something that "doesn't exist" the p.i.z.z.a references seem to pop up *really* often and in the darndest places.

One of the reviews:

The author Adam Rubin was asked by Saya Weissman in an interview on Digiday, "As a single, childless male, why [write] children's books?" He answered, "There is ... a subversive element that appeals to me. In fact, before I started writing [the first children's book] 'Those Darn Squirrels,' I was working on an X-rated comedy show at the Annoyance Theater called 'Dr. Amazing: Your Country Needs You.' It was named the 'Best thing to do in Chicago while high' by Time Out Magazine. So, despite my mantle as a children's author, my sensibilities are not exactly G-rated."

The book is basically about two groups of people. The first group has secret parties doing secret things that the second group objects to. Those in the second group are spoilsports who try to stop the parties.

There is an illustration with a slice of pizza on the raccoon's crotch (see attached photo), which is currently a popular concept on the Internet.

Lots about this book on the Internet. Watch the videos. Spread the word. Push back.
