How I see it, a sandwich is made up of the following:
-Two slices of bread
-A layer of animal meat
-Condiments
All of these check out for hotdogs, except for the following differences:
-Sandwiches have an up and down orientation. Our jaws and our clefts sink into the bread first. We eat hotdogs from an angle where the meat is bit into before the bread
-Sandwiches can use any kind of meat with any kind of bread and are thin enough to wobble and fold without breakage. Hotdogs and by extension burger patties do not have this utility
-Finally, hotdogs need boiling for the most part and have uses outside of the bread combination. Not to mention that the bread type for hotdogs are cheaply done and inferior for other non-hotdog meats.
At this point, it would be like arguing that crustaceans and arachnids are one and the same, and even though they share a lot in common, there are enough differences that they cannot be in the same class. The hotdog is a culinary cousin to the sandwich, but they are not 1:1
I was going to make a Captain America: Civil War joke with that, but Cyndane's persona is a card-carrying villain, so it'd make more sense if Moydow and Cyndane were the "Thor" and "Loki" of our cinematic universe respectively :v
Yep! You'd glow 'n ****. Think the Hulk, but without all the anger and muscle.
