Do you tend to buy books (magazines, etc.) if you see a good-looking man or woman on the cover, sporting a loincloth?
I admit that I've judged an occasional book by its cover, and been disappointed. Occasionally, I'm happy to have found a good book behind the cover... I'm reminded of one that I bought in my teens--Blue Adept, by Piers Anthony, that had a nicely-built young man in a blue kilt(?).
