A number of large subjects (art, biology, chemistry, economics etc) are tackled though the device of constructing short (usually between 1 and 5 items, occasionally a few more) lists under rather self-consciously funny titles and then providing a paragraph or two on each item. Just for fun the odd list of facts and figures are thrown in.

Examples of typical lists include: Fantastic side effects of neutering, Religious mysteries solved by chemistry, Women who shaped world religions, Religious rituals that hurt like hell, Reasons that you are an unreasonable reasoner.

There is a fair amount of American student/schoolboy humour - your enjoyment of the book will be determined by whether this appeals or not.
