Have you ever stared blankly at your kids when they've asked why the sky is blue? Or clumsily changed the subject when they've wanted to know why the wind blows? If you're done with school, it's likely you're also done knowing the difference between an isosceles and equilateral triangle, and you probably leave participles dangling all over the place. Well, not anymore! Thanks to professional know-it-alls Foley and Coates, you can now gain back your self-respect and actually show those kids a thing or two as you tell it to them straight (and not make it up from fragments of facts you kind of remember).
