Certifiable Mad Genius poster (16x20")

I Have a Death Ray, and I Know How to Use It! If you've got it, flaunt it! And by 'flaunt it' I mean, of course, 'Make them grovel in the dust before the machinations of my unmatchable intellect!' Muahahahaha. Mad Geniuses, you know who you are. Why not ensure that the rest of the world knows it too? And how better to begin the unstoppable process of day-rueing than by wearing one of these fine shirts on the morning of The Day That Shall Be Rued? Ah. Yes, yes indeed. And we're not just talking 'Mad Scientist' here, are we? For the world may tremble just as fearfully before the awesome power of the Mad Plumber, the Mad Data Entry Technician, or the Mad Receptionist! Yes! Yes! Our Time Has Come!
