Roy-O : Electric Shock

One of my hobbies(I guess you could call it a hobby) is scouring the internet for useful and worthless information.  I love Wikipedia and I get a lot of information from there.  I was reading up on Roy-O today and found this in his section from Wikipedia which I found interesting...

In 1999, when Oswalt was at the Class A level in the Midwestern League, he suffered an apparently serious shoulder injury. After a month of pain in his upper shoulder, Oswalt was convinced that his shoulder was torn. Shortly thereafter, he was checking the sparkplug wires on his truck. He touched one of the sparkplug wires, causing the truck's engine to start. The truck's electric current flowed through Oswalt's body, and consequently the muscles in his hand tightened on the sparkplug wire. Unable to let go of it, Oswalt grapsed the wire for almost one minute. Oswalt then claimed his foot slipped off the truck's bumper and he was finally "thrown off." After the electric shock, Oswalt told his wife that his shoulder's condition improved and that he no longer felt any pain. Oswalt claims he has not felt any pain in his shoulder since the incident.
