What is the word “madness” doing in the first chapter’s title of Automata Theory, Languages and Computation by Hopcroft, Motwani, Ullman?

The chapter’s title is “Automata: The Methods and the Madness”. This title came along in the second edition and remains in the third edition. In the first edition, the the second chapter’s title is “Finite Automata and Regular Expressions”.

The word “madness” doesn’t show up anywhere else in the third edition. Why is the chapter named like that? I haven’t read every word of chapter one, but it doesn’t look like there’s any explanation in it.
