A friend of mine IM'd me with this link as proof that there is a book on EVERY topic.
Adult Video Business: How You Can Find Attractive Women to Star in Your Own Adult Films, Make Money, and Quit Work in 7 Week. That's right. It's a HOW TO book on porn flicks.
If ya check out the "also bought" section, you'll notice there are several other similar titles. Get How to Become a Porn Director or Sex & Camcorders: The Complete Guide To Producing Low-Cost, High-Profit Adult Videos & DVDs or 1-2-3 Be a Porn Star! A Step-By-Step Guide to the Adult Sex Industry or even better... Coming Attractions: The Making of an X-Rated Video. heh. One must give a little thought to the title on that last one. ;)
Seems that there's a whole Porn Industry library of books out there.
As if that's not enough... you should really check out the rest of the stuff that Amazon thinks is relevant. Such as the link to info on Free Government Grants (that's right, get a gub'ment check to finance yer porn) or the selection of music that they consider "Similar Items." (Does Shania Twain know about this?!)
At any rate, this book wins my award for Best Book to "Accidentally" Leave Out When Friends and Family Visit.
