I've Always Wondered About That Rhyme 10 in the Bed

I was trying to get a book, I mean, I can show you or tell you about it later. It was a book written by Martin Waddell and other illustrators had given up on it. And I thought of wanting to do a book about that as a side thing while I was struggling to make another story work. So I went in one day and said, I've always wondered about that rhyme 10 in the bed,. What on earth was it about? Why were they, why were people falling out of bed? You know, what was it?
