Each chapter is written by a different kid, in a different typeface, ending with commentary by Tommy (the objective researcher) and his friend Harvey (the doubter who calls the figure "Paperwad Yoda"). The sixth-grade voices are real and funny, and the margins are decorated with funny sketches in the style of the Wimpy Kid books.
The show-don't-tell in this book is wonderful. Even Tommy thinks he's making his case study to find out if he should risk "making a fool" of himself for Sara, when really the book is about social pecking order and how it's determined. Tommy sees his specific dilemma but not the bigger picture, which is there to be picked up but never forced. Dwight, of course, is anything but dumb; who he really is (clever enough to give the Yoda advice) is there to be seen for those who will see it, yet any who do see it will think it's their own idea that Dwight's okay socially, which will bring Dwight better regard and more self-respect than trying to mimic or run after the cool clique would.
The humor in this book is funny rather than derogatory, and the cultural aspects of the story hit the bull's-eye: the Yoda figure is just the type of thing that can capture all sorts of attention among sixth-graders for a couple of weeks or so. Origami Yoda folding instructions included. A fun book with a subtle, realistic message.
