It's a shame Mr. Chipman didn't have time to get into how Superboy wasn't really a clone of Superman, but only a clone of as much Kryptonian DNA as the evil cloning facility Cadmus could understand plus half the DNA of Cadmus's evil boss, except years later it would turn out (read: be retconned) that the evil boss thing was a lie and the human half was actually Lex Luthor...
