The Templeton Twins Have an Idea is the funniest book I have ever read.
In every chapter there is a little box with questions for review written in it. One question that will give you the idea of the writing is this:
"Why is it a good idea to call something that sinks a sinker? Write your answer in the form of a brief opera."
The entire book is written with side comments and questions and editorial comments like:
"actually what the man had said was let's do it and then review it but John misheard his snappier version. It's just as well, don't you think? Don't you believe as I do that things should be as snappy as possible? Oh please. Yes, you do."
The Templeton twins left me laughing my head off!
