The Know-It-All has to be one of the most entertaining and informative book reports in existence. It is charming, humorous, instructive, fascinating, even kind of inspirational. But Jacobs’ book is more than that. He puts it all into the context of his life, and a text that could have been utterly dry winds up charming us with Jacobs’ honesty and vulnerability. Jacobs is courageous enough to risk looking stupid by sharing his quirks and insecurities . . . and he wins the gambit. He comes across as nothing short of endearing.
