I have searched the seasons to find the episode where Fred is indignant because Wilma told him he would not be able to live with a person like himself. Somehow a clone of Fred is created and Fred does not get along with his clone. He begs Wilma to get rid of the clone, but she makes him admit she was right first...That is my memory of the gist of the plot. I cannot find an episode that matches such a plot.

Does anyone else remember an episode like this? Would you know the season and title?
