Two unlikely crusaders, Warlow, a brash, abrasive businessman and McGoohan, a "bleeding heart" hack journalist, team up to tackle the world crisis of obesity with a simple solution. Sex. Lots of it. Up the frequency and the intensity and the problem will melt away. The world should literally Shag Itself Thin. McGoohan thinks this is one of the great causes of our time, while Warlow has dollar signs in his cash-register eyes. The way they tackle the business of toning the modern plump body is a humorous romp through life, love, sex, books and money.
