Too Naked For The Nazis - a book about the career of a vaudeville trio - has won the Diagram Prize, awarded to the oddest book title of the year.Author Alan Stafford had nominated his own book for the award run by The Bookseller magazine.
It beat Reading from Behind: A Cultural History of the Anus, with 24.8% of the public vote compared to 24.3%.
Stafford does not win a cash prize, but instead receives "a passable bottle of claret".
His book is a biography of musical hall act Wilson, Keppel and Betty - said to be "the inspiration for the Chuckle Brothers" - while Reading from Behind is an academic text.
Other works on the seven-strong shortlist for the prize, now in its 38th year, included Transvestite Vampire Biker Nuns from Outer Space and Soviet Bus Stops.
