Gleefully providing ammunition for snarky readers eager to second-guess misguided beliefs and commands of grown-ups, Rondina dishes up the straight poop on dozens of topics from the cleanliness of a dog’s mouth and the relationship (none) between French fries and acne to whether an earwig could really crawl into your ear and eat your brains. Since she cites no readily checkable sources—support for assertions comes in the form of quotations from experts in various fields, but there is no bibliography—it’s hard to tell how accurate some of her claims are—it would be nice to have a citation to the JAMA studies that debunk the sugar-hyperactivity connection, for instance—and too often she provides only an unsatisfying “You Decide” instead of a clear “True” or “False.” Still, it all makes painless reading equally suitable for casual dipping or reading straight through, and Sylvester’s pen-and-ink spot art adds further light notes to every page. An extensive closing catalog of familiar “Parentisms”—“I’m not running a taxi service,” “Because I said so, that’s why,” etc.—adds a chuckle-inducing lagniappe. (Informational ephemera. 9-11)
