The book was called Everything Men Understand About Women.

Upon opening it, the reader found 100 blank pages. Get it?

Very funny. But it gave T. J. Jefferson an idea. If men know nothing about the fairer sex, then why not go straight to the source? After all, if your toilet is backed up, you don't call your dentist, you call a plumber. So he asked strangers (and even some celebrities, such as Madonna, Shakira, Demi Moore, and Cameron Diaz) to fill the blank pages of his book.

In That's What She Said, Jefferson shares 100-plus tips he's gathered from women of all ages and backgrounds in a collection of entries in their own words that are offbeat, funny, sometimes mean, often poignant–but always honest. For men, it's not a book on how to get a woman to go home with you but on how to keep her attention once you have it. And for women, think of it as an entertaining look at what other ladies are going through. You may find vindication ("amen, sister") or put it down, relieved that you aren' t "as crazy as her" or that your man isn't a complete cad.

Organized by topics, including love, sex, beauty, lying, and listening, this is the ultimate look into the mind of today's modern woman.
