"Do tell."
It's been awhile since I read that book, but it's a collected series of cartoons with his commentary between the strips.
A good portion of it was his recounting his protracted battles with editors and others who tried to compartmentalize his strip. While I certainly understand the desire to remain true to what he obviously considers an art form (he's not alone in that), a lot of it comes across as overwrought, bitter, and antagonistic. At least it did to me.
