Your declaration confounds the evil mage, his face contorting into a mask of horror as you pick up the can. Not noticing his discomfort, you pop the top and down the soda in a succession of quick gulps, rather enjoying the flavor despite your inability to taste anything remotely resembling 'lime' within the concoction.
What neither you nor the mage could know, if I may presume to be both rather omniscient and digressive for a moment, is that the very same morning upon which you decided to take a walk in an attempt to forget the complications and worries of modern living, Bernadette, the long-suffering wife of the evil mage whose evil hot dog stand you have decided to patronize, had come to the conclusion that her marriage to the evil mage had fallen into such disrepair that it could never be salvaged. However, upon much reflection Bernadette decided that divorce, though seemingly the natural conclusion of the majority of modern marriages, would be far too damaging to the young children the two had sired. As a result she hatched a plot which she believed would be far less traumatic, that being the timely and extremely ghastly death of her husband at the hands of some random fellow who would temporarily assume the form of the legendary beast known as the hydra. Thusly, Bernadette spent the greater portion of the wee small hours of the morning concocting a brew which might become the proverbial arrow with which to fell her Achilles. Unfortunately, while an expert at crafting evil potions and the best little raspberry torts you'll ever happen across, Bernadette had never learned the art of subtlety, hence the rather conspicuous name of the soda which you chanced to quaff at the evil hot dog stand. For all purposes, this fact would ordinarily have been a major setback to the planned execution of her husband. Luckily, through a major working of universal happenstance the evil mage had not spied the obviously-named cola, due in part to a facial injury sustained during an evil football game in evil high school which had left him partially blind in his left eye.
Completely unaware of this sordid history, you stand in front of the evil hot dog stand with a pleased look on your face, relishing in the satisfaction that only proper hydration from a delicious beverage can bring. Suddenly, from within some deep partition of your body you feel a welling up of some unknown force. Fearing that perhaps your speedy consumption of the tasty cola has somehow shattered your coccyx, you wait with trepidation to see what will come of this roiling within your deepest being. Bubbling up from within, you feel it travel through your body and upward through your chest. Without warning, a breaking point is reached as the strage energy, refusing to be restrained by any biological barrier, rumbles its way directly from your chest and out of your mouth!
"Burrrp."
Looking at the owner of the evil hot dog stand, you sheepishly cover your mouth and mumble an apology. For his part, the evil mage simply stares at you as if you've grown a second head. Thinking it rather rude that the man refuses to accept an apology for a common gastric expulsion, it suddenly dawns upon you that the neckhole of your shirt has suddenly become rather tight. Turning your head and trying to get a look at what is causing the disruption, your forehead smacks with some force into a rather hard object. Pulling your neck back as far as it will go, which for some odd reason seems to be a little farther than it should go, you come face to face with what for all the world looks to be a duplicate of your own handsome visage. Staring at this extra noggin which has quite rudely violated your personal space and, quite eerily, having it regard you with a stare of its own, you do take note of some differences with what you normally would see in the bathroom mirror, such as the slightly protruding fangs, longer neck, and mildly scaly skin that it possesses.
Turning to regard the owner of the evil hot dog stand and preparing to demand answers, you find anything you might say cut off by a query voiced by your newly-grown extra head, demanding to know what the evil mage has done to him!
