Parody for Dummies

I recently ran across this item on Amazon.com: a book entitled Ventriloquism for Dummies (Black Moss Press, 2002). It doesn't appear to be approved or licensed by Wiley, but it does look a lot like Wiley's Dummies books.

(A few bloggers have previously made note of this book, including The Honest Hypocrite and J-Walk. Other bloggers have suggested the title, apparently without realizing it already exists -- see Jonathan's Wacky World and HappySinner's Greenehouse.)
