You TOTALLY used CliffsNotes at one point. You know it, I know it, and (sorry to inform you of this, but) your teacher knew it as well. Whether it was to supplement your knowledge of a book for a test or to fake your way through an entire thesis paper, you possessed at least one copy of that iconic yellow and black book. And I’m sure at some point, you picked up that slim tome approximately 1/8th the size of the book you were actually assigned to read, and wondered… Just who the hell was Cliff???
