The Diagram Prize is awarded by The Bookseller each year to the book with the oddest title. To give you an example it was won last year by If You Want Closure in Your Relationship, Start with Your Legs by Big Boom (is there a separate prize for the oddest author's name?). This year they're casting back over past winners, much like the Booker of Bookers, to find the oddest of the odd, or Diagram of Diagrams. The Guardian has an article here and a pictorial selection which can be found here so you can pick your personal favourite. As someone who is constantly removing cat hair from clothing and carpets I feel inspired by the book above to create a new wardrobe. Failing that I could always read Highlights in the History of Concrete.
