This book opens with an anecdote about a man courting a lovely woman who (upon seeing his over-endowed penis) screams, runs away stark naked, breaks her neck, and dies. He then ends up in the hospital, having hit his member several times with a hammer in frustration at his cursed existance. Here, he meets the priest who helped him write this book. The priest also suffers from "OMG" (Oversized Male Genitallia) and offers advice and ways to deal with the problems it entails, like the possibility of veins expolding during intercourse, dizzyness during erections (because of all the blood required to maintain one) , whether or not to get reductive surgery, and other entirely legitimate-sounding medical dilemmas. There were even personal anecdotes from other sufferers, and a self-diagnosis quiz.
After spending the afternoon in a deep state of confusion (surely over 8 firm inches is not all that abnormal?), it then took me 20 minutes of Wiki and google to confirm that it was, in fact, a joke.
Apparently, Borders didn't get it either...
