I would think that the next salient to exploit would be a lengthy dissertation on the evident shortcomings of his ancestry...
So, we have established that are both stupid and ugly. It has also come to my attention that your lineage is of questionable origin. One can only begin to wonder from what depths your ancestors crawled. From under which offal-covered, sulpher encrusted, petrified dinosaur turd you slithered. I expect that you were sired by a Cave-Troll and your mother was an Ogre. Perhaps a Cave-Troll buggered a platypus and the resultant goo that was not retained inside the platypus oozed into a tar-pit, thereby giving the impetus for your apparent spawning. A Leprechaun has a better lineage than do you.
