When Lex Luthor aimed a Duplicator Ray at Superman, without his knowledge, the result was Bizarro. An imperfect double of Superman with Super powers, but opposite from the Man of Steel. For instance, Green Kryptonite will kill Superman and not harm Bizarro. But Blue Kryptonite will. Superman's Fortress is in the Artic, Bizarro's is on a square planet in the Desert.
I understand that the same kind of thing happened to Al Gore.
Hah! Planets are not in deserts. Deserts are on planets. Guess those comic strip guys don't think of everything.

BTW, this is SauronOfMordor's daughter. Fascinating subject, this is. Don't really understand it...but then, few people do.
