How curious. I've been keeping a list of amusing search-engine referrals that might point to a stricter rating, but I'll share that with you another time.This rating was determined based on the presence of the following words:
* dead (3x)
* ass (1x)
The "ass" reference is here and, despite the proximate mention of dung, it just means donkey. Considering how often I refer to the Dead Sea Scrolls, I have no idea how the 3x for "dead" was computed. But if all of them were counted, the site probably would have figured PaleoJudaica was a zombie movie.
