I never skip right to the end of the book, only ever further down the page, usually to see whether what I think is going to happen actually does, as I can't bear the suspense any longer!
I think the only time I've ever been tempted to skip to the very last paragraph of a book to see how it ends was when I was about three quarters of the way through The Historian. I didn't though - I got my OH to read it somehow thinking that would get rid of my suspense!
