Herschel Walker is Richard Simmons?

In an exclusive interview on "Nightline" last night, former NFL Running Back Herschel Walker admitted that he has a disease called DID, formerly known as multiple personality disorder. In his just released book, "Breaking Free" the 46-year-old Walker delves into his struggles with a mental disorder of which he had a dozen distinct personalities, one being the famous exercise guru Richard Simmons. Following his retirement in 1997, Simmons, errrr I mean Walker has been consumed by the disorder, even at one point playing Russian roulette with a loaded pistol while sitting in his kitchen. Walker's ex-wife Cindy Grossman, did not know about the DID until after their 16 year marriage. When asked why she was so clueless, Walker responded: "Cindy is extremely dumb. She was a cheerleader and married a football player, enough said. Now let's get those bodies in shape! Woo hoo! Focus, focus people! And stretch, feel that burn! Oh yeah!"
