The Best Book Ever Written

The Best Book Ever Written. Well nearly ever. Well it could be if we could finish it. Please help us finish this book and make it the best book ever written. An interactive story for children.
To the reader :
This book is meant to be an interactive experience between the reader and the children listening to the story.
When the children suggest the naughty rhyming word, as they will invariably do, the reader can respond with something like
"Oh you can't say that, that word won't do.
This book is to be read, by children just like you."
OR
"What did you say? That's not what this book is about.
That is a word I think, I'll most certainly be leaving out."
THEN
"Now let's continue on with the story."
