Where to find Party Like a Rock Star in the bookstore

When I go into a bookstore, I always check to see if it's carrying Party Like a Rock Star, and in which section it's located. So far, no two bookstores have filed it in the same place. I've seen it in:

-Pop Culture
-Men's Studies
-Self Help
-Gay Literature (???)
-Excess Culture
-Weddings and Etiquette (???)
-Fashion

The only place I haven't seen it is where I assumed it would be filed- Personal Finance.

So if you want to check it out in your local bookstore, you're probably going to have to ask them at the counter where the heck they put it.
