A book about the evolution of genitals 'Nature's Nether Regions' by Menno Schilthuizen is one of the seven books up for Diagram Prize 2015 for the oddest book title of the year.
It is up against menopause memoir 'The Madwoman in the Volvo: My Year of Raging Hormones,' 'Divorcing a Real Witch' a practical guide for ending pagan relationships, an investigation of the species 'Where do Camels Belong?,' and 'The Ugly Wife is Treasured at Home,' an expose of love and sex under Maoist rule in China.
'Strangers Have the Best Candy,' an account of speaking to strangers, and the academic papers from a two-day symposium of concrete pavements 'Advanced Pavement Research' complete the shortlist.
The Bookseller's Horace Bent said that this is one of strongest years he has seen in more than three decades of administering the prize, which highlights the creme de la creme of unintentionally nonsensical, absurd and downright head-scratching titles.
Bent added that ultimately, it is a stunning collection of books and let other awards cheer the contents within, the Diagram will always continually judge the book by its cover (title).
Members of the public can vote for their favourite on 'We Love This Book' by 20 March, but there is no prize for the winning title and the person who nominated it will receive a passable bottle of claret.
The winner will be named on 27 March.
