An iPhone app promoting Hachette Book Group's "The Man's Book: The Essential Guide for the Modern Man" has nabbed the second place spot in the overall free-apps category in the Apple App Store.

The company built the "Urinal Test"--an iPhone game that tests one's ability to navigate a crowded bathroom--as a promotional tool for the male-centered handbook by Thomas Fink. The App debuted on April 16, and has earned a coveted spot on the App Store homepage.

Here's more about the book: "The answers to every man's burning questions are within these pages, from the morning wet shave to the whiskey night-cap, from hunting deer with a .30-06 to wooing women like 007. At a time when the sexes are muddled and masculinity is marginalized, THE MAN'S BOOK unabashedly celebrates maleness."
