Rule #13 - Keep away from people named Mayson.
Rule #14 - A kiss/declaration of love is a good way of keeping him in Metropolis when it looks like he's going to run away.
Rule #15 - Failing #14 - look into microchipping/Lojacking him. It'll make him a lot easier to find.
Rule #16 - Ask youself if any of his lame excuses *really* make any sense. When in doubt, investigate. If it sounds too bizzarre (ie Cheese of the Month club) it probably isn't true.
Rule #17 - You can use "lunkhead" as a term of endearment with him.
Rule #18 - For sex, just feed him pasta.
Rule #18a - When following the above rule, be warned that he may be insatiable. He *is* Superman, after all.
