Book excerpt: When grade-eight science-project time rolls around, J.J. Murphy skips the beakers and the papiermâché and dives into research about jerks. And idiots. But mostly jerks. By his own estimation, his science project, On a Scale from Idiot to Complete Jerk, is groundbreaking, exhaustive, highly scientific and seriously worthy of bonus marks. Beginning with the dawn of humankind and concluding conclusively with a very cool pie chart, the project dissects the elements of jerkosity through extensive case studies and scientific illustrations. It explores the who, what, when, why and how of jerks and, more important, peppers the lively research with sciencey-looking graphs and charts that reveal a lot about J.J., his family and friends, and the jerks of this world.
