I purchased this book concurrently with the duo's previous book - Understanding Philosophy Through Jokes. That one was as advertised - providing a gentle introduction (or perhaps re-introduction) to, say, the iedas of Rudolf Carnap in a well-written and often humorous-enough way.
This book ("Aristotle and an Aardvark") attempts to do the same for "political doublespeak" Unfortunately, it falls flat and seems dated already, quite soon after its original publication. Even though this book shares the same basic format as the previous one, this one suffers from three fundamental flaws:
1. If you're a likely reader of this book, you will already likely have encountered the vast majority of examples of quotes in your regular internet browsing over the last few years. The specifics of Kant or Schopenhauer illuminated in the previous book required at least a philosophy major's background knowlege of philosophy. The "research" for the factual content of this book could more or less be summed up from skimming CNN and watching the Daily Show.
2. I'm left-of-lenin liberal, but reading a book teeming with wink-wink ad hominems about George W Bush and co seems dated and gratuitous. I was expecting something more timeless, along the lines of the Philosophy book. Instead, we get jocular Tom Delay bashing.
3. The "theoretical" content of this book (which, by the way, would probably be more accurately called "... through theory and jokes", though that sounds rather unsaleable) is weak. It's largely an abridged list of standard logical fallacies. Unlike Wittenstein, this tends to be something that the target audience already knows. As such, the theoretical framework largely exists to make yet more George Bush jokes, interspersed with a slag on, say, Ray Nagin for balance or something.
On the plus side, the cartoons and unrelated jokes are good. There's probably something there you can work into a talk or lecture if you're an academic.
Overall, I expected something much more enlightened, witty, and intelligent.
In case it's not clear already: read the authors' other book, and probably give this one a miss.
