The most-watched telecast in Animal Planet's history is about mermaids.
Sunday's "documentary" Mermaids: The New Evidence delivered 3.6 million viewers, shattering the network's ratings record. Yup, even bigger than the Puppy Bowl. The program is not only a hoax, but a sequel to a hoax -- to last year's rather effortlessly debunked Mermaids: The Body Found, which fooled more viewers than you'd think.
