USA Today spoils all the fun with "Fooled again by 'Mermaids: The Body Found' on Discovery? Discovery Channel aired Mermaids: The Body Found last night and it seems it got a lot of people (No. 1 on Google Trends) wondering if the mythical sea creatures could be real, particularly thanks to a scene showing a boy finding a freaky creature on the beach. In describing the show, Discovery says, "What if there's a kernel of truth behind the legend of this mythic creature? Is the idea of mermaids really so far-fetched? Maybe so, maybe not. The show itself, though science fiction, is based on some real events and scientific theory."
