Bigger and better and more indispensable than ever, it's Richard Smith's tongue-in-cheek humour classics in a brand new format perfect for gift-giving. Completely revised and updated to include topical issues like metrosexuals, Viagra, second honeymoons, and cell phone sex (in the car, on the bus). Funny as hell, and now comprehensive, from bathing together to banish the blahs: 20 calories burned; with a rubber duck: 40 calories; with the au pair: 592 calories - to putting on a condom: while still in the restaurant: 27 calories; while ringing her doorbell: 66 calories; while asking her out: 200 calories - to thanking partner for a wonderful night: signing your note guess-who?; 5 calories, if partner has no idea who it's from: 200 calories.
