"I demand to know what you've done to me!" your new head shouts at the bewildered evil mage at the evil hot dog stand. "My teeth feel really funny for one, but look! Are you telling me that I'm going to have a second head floating around for the rest of my life? Always bashing heads with myself? Huh? What if I don't want to always look at my own ugly face? Did you think about that? Well? Did you? No, I didn't think so! Why, -"
"Uh, excuse me," you interject. As interesting as it is to watch yourself tear a strip off of the poor hot dog vendor, you don't want to see any innocents get attacked by your own fanged head. Your other face turns to look at you. Your necks are only about ten inches long, which is a lot longer than before but still doesn't give much space for a head-to-head talk. You see again that your other head has slightly protruding fangs, and run your tongue across your own teeth. Your teeth still feel normal enough.
"What's wrong?" your other head demands somewhat irritably. "Are you saying you're happy about this?"
"Well, no, not particularly," you reply to yourself as the evil mage stares at the two of you with unmasked fear. "But I'm the original, I think. See? I can move my- er, our arms. Can you?" You aim to scratch the back of your head with your left hand, but your hand hits the back of your extended neck instead. Is your neck slightly scaly, too? It feels right enough, with neck hairs and all. You use your right hand to feel the back of your other neck, and yes, the parts where you saw a faint glint that looked like scales feels smoother (slipperier?) than your normal skin.
"Stop that! Let me try!" Your other head frowns in concentration for a bit, and finally gives up when it becomes apparent to him that he's just along for the ride on your shoulder. "Yeah, alright, so what's your point?"
"Well, you wouldn't be here at all if not for him, so why are you so angry?" Your other head pauses to consider this point and nods in half-hearted agreement. "Anyways, I'm still a bit hungry," you say as you turn back to the evil hot dog vendor. "Could I get another hot dog to go, please?"
The evil hot dog vendor, completely baffled and confused, obliges and prepares another hot dog for you. "I want one, too," your second head demands. You shrug, and agree. "Right - make that two hot dogs, please."
You turn and start wandering away from the evil hot dog stand with the two hot dogs you ordered. You start eating one, and try to pass the other to your other head. Your second head makes a snide remark about not having any arms to call his own, so while you're eating one hot dog from your left hand, your other head happily starts eating the other hot dog from your right hand. Not the most convenient way to eat, but it works well enough.
As you are leaving the park, you begin to feel another bout of gas building up in your stomach. The pressure builds to a very uncomfortable level before -
Brrraaarrp!
"Excuse you."
"Excuse you."
