'The Portable Curmudgeon' is a lovely collection of curmudgeonly quotes aimed at purging society of its inner demons through deliciously wicked laughter. This started as a 'bathroom book' in my house, but I soon found myself hooked and spent half an afternoon reading it straight through. The occasional biographies of and interviews with some of the featured curmudgeons are a nice touch. Unfortunately the text is rather seriously marred by frequent errors; you would think the curmudgeonliness of the book's spirit would extend to a discernment in typesetting, but apparently not. I have not got any of the sequels, but I intend to lay hands on them as soon as I may.
