A guide on how to cope with awkward romantic situations wins the quirky Diagram Award.

"How To Poo on a Date: The Lovers' Guide to Toilet Etiquette" collected more than 30% of the total vote in an online poll, beating out other finalists "Are Trout South African" and "Working Class Cats: The Bodega Cats of New York City."

Prize Director Horace Bent describes the book as "a manual that can help one through life's more challenging and delicate moments."

The Bookseller, a British Trade magazine, has presented this prize since 1978. Previous winners include "Bombproof Your Horse," ''Living With Crazy Buttocks" and "Crocheting Adventures with Hyperbolic Planes."
