Of course, you don't really evaluate a book like this. You just read it for enjoyment.
Ever have a hankering to kill your computer, cheat a parking meter or place a gypsy curse? That's my point exactly: you won't want to do all of these but you'll surely have wished you knew how to do some of them at one point or another.
This book adds some genuine funny to its descriptions of how to do all of these and 98 more. It doesn't really recommend you do them exactly- it's tongue in cheek. (It'll probably tell you how to do that too if you don't already know how.)
File under "F" for Fun.
