The comprehensive 521-page book has sections titled Cleanliness in Greece and Rome, Hair and Fingernails, Overcoming Eye Faults, The Nose Route, Making the Most of Your Feet, In the Woods and Fields, What to Eat, What Not to Eat, Drugs That May Harm the Heart, What Happens When You Are Asleep and Skill in Walking.
The obvious implication of this six-panel story, made with subtle stick-figure details, is that Bill is stronger, faster, has a better posture and combs his hair. Arthur is weak. He slouches, trails behind and has Bad Hair. Arthur will lose the job. Arthur will lose at life. Arthur will slouch off into the forest and become Slender Man, feeding on unwise children and thus keeping Darwinism barreling forward.
Arthur might forget his True Name, but he will never forget this day.
That's a lot of clever storytelling packed into a six-panel cartoon, don't you think?
