You could argue that Bart Gunn really got the shaft by the WWE and as such you forget that he had a decent run. He entered the WWE with his kayfabe brother, Billy, and they would win the World Tag Team Championship three times. When the team broke-up they saw more money in Billy and eventually (albeit in another tag team), he became the much bigger star when he was in the New Age Outlaws and finally D-Generation X.
There were not that many female wrestlers in the 1960s and 1970s but those that were able to make it was among the toughest women in the world, but few of them could hold a candle to Kay Noble.
