At first, I bought this book only because its cartoon drawing and I like humor a lot. Yes, indeed it contains a good humor material and made me laugh.
However, for several chapters I found a very similar resemblance with actual situation in my office, especially chapter about "Employee strategies", "Performance reviews" and "Engineers.." ( I am an engineer, that's why I knew that Scott's view of this area is accurate).
Then I realized that this book not only offers funny cartoon drawing and naughty advices, but also good advices!
The secret is, you have to know which advices you could use and which you shouldn't. You can determine that with a combination of your office situation analysis, your IQ level, whether your boss also has this book or not, and ...luck! In short, this book is recommended
