He knew he didn't exist and had never existed, which was quite something for a fictional character. When he met someone who smugly claimed that by knowing all the world's a stage etc., she was freed to be the author of her own play he laughed and said, "Never!" This knowledge would always arrive to get him out of a jam, but even if the fallout of its self-certainty lasted a little while it would inevitably turn into the theme of a further story, the story of someone who knew, or thought he knew something, who had a certain attribute, and who hence knew nothing at all. And like every fictional character, he would stumble into a fresh jam.
