When my son was 4, we watched Xena Warrior Princess, and Hercules on tv, because they were pretty clean as far as language and the fantasy fighting wasn't really violent. Once myself and his two sisters were sitting in the tv room watching Xena, when he came running in with his play sword and a cape. "Who are you?" we asked. "My Xena!" he said proudly. I said, "oh no honey, you're Hercules." He looked at me with utter contempt on his face, "NO Mom, my Xena." explaining patiently, as if I was too much of a dork to know that Xena kicked butt better than Hercules!
