DO – Use Kryptonite to build a whole new continent, dump wigs in the hands of little girls, cut car breaks, manipulate old ladies, generally act like a camp know-it-all.
DON’T – Stab Superman with Kryptonite and leave him to die in the ocean. HE’S SUPERMAN FOR CHRIST’S SAKE! You better make sure that mofo really is dead before you dispose of the body.
