Perhaps, my expectations of this book were too high. I was looking for an amusing, yet somewhat historically thorough book. It did indeed have many underworld entities I had never heard of before. However, there were also ridiculous entries that in my opinion, were wasting space: comic books, video games, David Letterman (for saying, "this show's going to hell"). What is that? The only entry I immediately recall not finding is "Diablo"... they at least could have put it under video games... I mean, they had "Doom".
