Taking 'Dummies' a step further, they now have a book on that subset of the Dummies population that considers themselves a dummy amongst his peers, or a 'Dummy's Dummy' if you will.

At least, thats what I think of when I see Mp3 for Dummies (For Dummies). Heck, they even lowercased the p in MP3, and capitalized the second For.

Still, things could be worse... (from the same publisher, I have to point out the hilarious Data Structures & Algorithm Analysis in Java by Sarah Michelle Geller. I want that book. I bet the exercises would be more fun, though I'd probably get annoyed every third page when she says "and this part had lots of gnar, so I asked Willow to do it."
