LONDON: A tongue-in-cheek book that purports to deal with an awkward but critical issue, How to Poo on a Date, scooped an award for the Oddest Book Title of the Year.

The winner of the Diagram Prize, awarded annually since 1978 and based on a public vote since 2000, beat other titles including Are Trout South African? and Working-Class Cats: The Bodega Cats of New York City.

The prize is run by The Bookseller, a British business magazine and website for the book industry.

“The public have chosen wisely. Not only have they picked a title that truly captures the spirit of the prize, they have selected a manual that can help one through life’s more challenging and delicate moments,” Horace Bent, described as “custodian of the prize”, said.
