If you read the book(HOW TO DRAW STUPID), here and there are some helpful tips. But in the main, his advice is this: "draw funny!" And how do you do that, as he states that "either something is funny or isn't"? Why, by looking at his brilliant cartoons, which he keeps telling us are funny and great. Most of which have been recycled, for what looks like the third time, from THE BAKERS, the art in which I think is way too Disney, but Baker says you want that! It sells!
He also foregoes tools information, saying "Draw on anything you want!" and mocks people who still use ink, forgetting that without his knowledge of Photoshop and the like(which he doesn't go into, and no tools info is unusual for a beginner's instruction book), those drawings "drawn on anything" might end up crap from a naive beginner.
I realize that using your own work is okay--Hogarth certainly did. And there is useful stuff to be found. I'm just saying the overall tone is that of a crass showoff and seems to never forget to plug his own books. This is the side of Baker I don't like.
