Query: A pretty good crytogram book

Cryptograms are on of my favorite puzzles and this one has very silly cryptograms. The puzzles are a good challenge and I can fingure most of them out, but you have to like silliness to stick with this one. I have had it for over a year and lost interest after a few weeks. It just sits on my shelf.
