Which books have the coolest and worst names/titles?

I've always loved the names of Joe Abercrombie's books but Last Argument Of Kings and The Wisdom Of Crowds are my favourite. Also love Ruocchio's Sun Eater series with Demon In White and (still not released) Shadows Upon Time being my favourites.

And even though I do enjoy her books, I've never been the biggest fan of the names of the books in Robin Hobb's Realm Of The Elderlings.
