Books like Be a Perfect Person in Just Three Days!

I made sure this was fiction before checking it out from my library when I was a kid. Even then I was wary of self-help books making specious claims. :)This is about a kid named Milo who is intrigued by the title of a book called Be A Perfect Person in Just Three Days. He's got a lot of problems at home and would love to become "perfect," but this book keeps ordering him to do weird things (like put a hunk of broccoli around his neck), and he's a little suspicious of the photos of the author (which do NOT suggest the author knows anything about being perfect). But he's also instructed to not skip ahead in the book, so he doesn't know what to expect. Unfortunately even though it's got its funny moments and hilarious images, it doesn't do much but teach little Milo that there's really no such thing as being perfect--especially if you do so just trying to copy what someone else tells you to do. I think when I was a kid I was hoping something cool would happen for him when really the book was kind of just trolling him. But "no one's perfect" is still a good message.
