    About the two layers of bread, does that mean that Subway sandwiches aren’t actual sandwiches? As the bread is connected at the side, really forming just one price of bread that has been folded. Or does it still count due to the ingredients being spread across the bread in “thin layers” unlike a tube shaped hotdog in a hotdog bun?

    Okay, so you know how they said something about chicken wings being a sandwich? Well, here's something that me and my friend thought of. A sandwich is something put in between bread, correct? Well, most chicken wings that you can buy are breaded, so therefor it means a chicken wing is actually a sandwich in a way. I HOPE TO GOD IM NOT RIGHT ON THIS!

    1. what if the bun tears in half? then its two pieces of bread 2. what about people who slice their hotdogs in half down the middle making two pieces? would that not be "thinly sliced meat"? 3. what about people who add cheese and condiments to their hotdogs? would that not classify as "savory mixture"?

    Hot dogs and sandwiches are NOT exclusive... one can be a subset of the other (hot dogs, in this case, being a subset of sandwiches). But hey, that's just a theory. SET THEORY. :)

    omg I saw the Food Theorists pop up on my dashboard and immediately peeked at the channel to see if it was really team theorist. after confirmation, i immediately subbed because we're filling out the logo now (RIP music theory from one of your gtealive streams though). I started with the fry theory because I love potatoes and ended with this one. the one I didn't really care for was about the kool-aid man because it was SO out there, but that's just my take. I think I'd like to learn more about food mascots like chef boyardee and whatnot. still! i'm super hyped for this channel, quarantine got me binge watching food shows.

    I think a good theory would be about the classification of food and how it relate to race and physical features. (like acksents and eyes and skin color) Or am I wrong.

    Wait, doesn't that dictionary definition exclude PB&J sandwiches as that's not a savory spread? Also, if a bun doesn't count as two slices of bread, then a sub/hoagie wouldn't count either.
