Boog is referring to a quote by French novelist, Gustave Flaubert (1821 – 1880):

“What I would like to write is a book about nothing, a book without exterior attachments, which would be held together by the inner force of its style, as the earth without support is held in the air, a book that would have almost no subject or at least in which the subject would be almost invisible.”

Boog began writing his autobiography in this strip.
