There is a book entitled "Everything Men Know About Women"
selling in the bookstores.
It is totally blank. 
THose types of books are always good for a laugh, but have been
around for ages.
I saw a book from Australia once called The Wit and Wisdom of
Bob Hawke...and the inside was completely empty, like yours.
Bob Hawke was the Australian Prime Minister in the 1980's, which
shows how long this idea has been around!
