A paper cover? (Or are you talking about something I'm not aware of?) Sure, but if I buy the "To Kill a Mockingird" cover and start reading another book, it doesn't change the cover.

The point I was trying to imply without saying it outright is that guys will take different books to places they'll be best received. There's an entirely different vibe in DC's "Adams Morgan" district than there is in the Shaw neighborhood, and the savvy pickup artist isn't likely to be reading the same book in both places.
