I heard about this book during a TV transmission and the examples I find funny ca. But once received at home, there is a lot of humor, but sometimes is not we understand or we pass 3h find what may be funny, or it looks like a prank caramel. Funny things 70%, 30% not funny Otherwise, there is research on the images, fonts and writings. A book has to offer rather than buy it. And in my opinion, it will quickly re-offer or resale.
