Nick jumps into the body of Olympic gold medal winner Jackie Joyner-Kersee and is coached by her husband on how to throw the shotput for a track and field competition. This isn't enough so he decides to cheat. He wears the jersey inside out, which imbues him with another athlete's powers. Meanwhile Elliott and Morgan learn that Nick and Morgan's grandfather was wearing the jersey inside out and the power was too great and it blew out his knee. They rush to tell Nick, who ignores them. He injures his shoulder but fortunately the injury is not permanent.
