A light, funny way to introduce yourself to the fundamentals of philosophy, or refresh what you were taught in school. I had a really hard time not reading a lot of this out loud to MT, and while he claimed prior knowledge of a few of the jokes, they were all new to me (I think, I don't remember jokes very well).
If you're looking for anything resembling an in-depth look at the different schools of philosophy, this isn't the book for you, but otherwise, I'd recommend it as both entertaining and informative.
