What Buttosaur Is That? — Andy Griffiths

Tyrannosore-Arse Rex Versus Tricerabutt:
Who Kicked More Butt?

Stenchtiles and Farthropods:
Which Smelled Most Foul?

Exstinktion:
How Did The Buttosaurs Get Wiped?

This book will tell you everything you need to know but were too grossed out to ask prehistoric butt-related life forms and the complex stenchology of their environment.

Never again will you look like a fool when somebody asks, “What buttosaur is that?”
