You’ll have to jump back to the late eighties, when most of these stories were collected. Things like microwave ovens and tanning beds were the height of new technology, so they terrified lots of people, and inspired the worst urban legends of the time. Didn’t we all hear of small pets being accidentally microwaved, and brides-to-be having their insides broiled from too many visits to the tanning salons? Some of the legends were so ridiculous nobody could have believed them, (I’m thinking of the “blow dried” bunny, dead, of course) but others, like somebody paying $250 dollars for the Mrs. Fields cookie recipe, were standard fare. Overall, the stories are lots of fun, but there’s too much discussion of where they might have come from, and how they might have evolved. I used to read Brunvand’s column in the Deseret News, and I always enjoyed it. I think his material is better suited to daily snippets, and doesn’t stretch out very well in book form.
