20/20: Medical Mysteries/Family Secrets

In the first hour, the Medical Mysteries reports include a college student who would get epileptic fits from hearing a particular rap song; a woman whose body exudes a fish-smelling odor; a girl whose stuttering was helped by a tiny ear device; and a look at some people whose bodies are not affected by the cold. In the second hour, a report on a man who, when he was a senior in highschool, was charged with sexual assault for having consensual sex with his freshman girlfriend. Then, an interview with Tori Spelling about her new tell-all book about her family. Next, a look at the untimely death of a Baptist preacher's wife - was she murdered by her husband? Finally, a man who claims that his father could be John F. Kennedy.
