This book looks at the humorous side of a wonderfully dysfunctional childhood of kid growing up in the 1980s that will inspire you to see your own screwed up past in a more humorous light.
What is a "normal childhood?" Does it include almost being murdered by your sister with an ax? Speeding around town in the back of a station wagon because your mom is chasing an "alien spaceship"? Being busted by the police for intent to light a pond on fire? Tackling your mom to the ground and wrestling a knife out of her hand because she was trying to kill your dad? While these stories may be unique, readers will be able to relate to the broader themes that are part of a normal childhood such as sibling rivalry, eccentric parents, doing stupid things, and frequently preventing one's parents from literally murdering each other.
Although some of the subject matter is not something one would generally laugh at, you have the author's permission to laugh. Life is too short not to.
