Sunny eventually caused the team's downfall, as she became the source of infighting between the two. When the Smoking Gunns lost their tag team title to Owen Hart and the British Bulldog in September 1996 at , Sunny left the team because she only wanted to be a manager for title holders (although she did not become Hart and Bulldog's manager). Billy, frustrated with losing both the title and Sunny, turned against Bart. Billy briefly feuded with Bart. After facing each other in tag team matches, the feud culminated in a one-on-one battle. During the match, Bart accidentally injured Billy's neck, forcing Billy to take some time off and drawing their feud to an abrupt halt. On June 9, 1997 Billy as Rockabilly defeated Bart on Raw Is War. Afterwards Bart left WWF.
