Mona Lisa Overdrive The cyberpunk novel by William Gibson is a great title. Also "The Dead Lady of Clowntown" by Cordwainer Smith. "Think Blue, Count Two" by the same author
Carlton mellick III has always been one for making great and daring book titles. I mean, who has the temerity to call a novel, The Baby Jesus Butt Plug, LOL Then he has other titles such as, Adolf in wonderland Satan Burger razor wire pubic hair The menstruating mall (Like wtf?) etc etc
My favorite is a Swedish one called Jag behöver dig mer än jag älskar dig och jag älskar dig så himla mycket, written by Gunnar Ardelius. A really long title, as you can see, which was translated (in the English version) into: I need you more than I love you and I love you to bits. I just love it because it's so unusal.
