Have you ever read the last page of a book before actually reading the book?

In other words, have you ever been so compelled to read the ending or last page of a book before finishing the entire book or even starting the book persay? I have never done this, but have known people who have and find it very interesting. I can only recall one book that I have read that actually brought it all together on the very last line of the very last page of the book. If you have done this… what book was it and why did you do it? How did you feel afterwards?
