Tonight, ABC's Nightline has an interview with former running back Herschel Walker about his battle with multiple-personality disorder. We find out that Herschel went so some very spooky places while in the throes of his disease, like suicidal thoughts and unpredictable violent urges. Walker's ex-wife, Cindy Grossman, was interviewed and she was also clueless about his condition and found about it only after their marriage ended.

"Well, now it makes perfect sense, because each personality has a different interest," Grossman told "Nightline". "This one has an interest in ballet, this one has an interest in the Marines, this one had an interest [in the] FBI, this one had an interest in sports.

"There was also a very sweet, lovable [personality]. That's the one he told me I married. He told me I didn't marry Herschel," said Grossman, who later in the interview recalled a conversation with Walker, "and the next thing I knew, he just kind of raged and he got a gun and put it to my temple."

The interview is to promote Walker's new book "Breaking Free," which chronicles his madness in all its Eve-faced detail . Those book signings should be really interesting.
