Nuh-uh!

I'm watching an episode of the Mentalist, in which the killer is caught because he knows that the whale dies at the end of Moby Dick, thus proving that he had read the book, and that he was mentally competent, and not "challenged" as he was pretending. Except, Moby Dick doesn't die! The whole premise of the show is based on a lie. Who is researching for this show??? Yeesh. Idiots.
