|BACONPØLSE isn't a sandwich, either|
Hot dogs fail the "followed by sandwich test," which is a thing I made up to determine whether or not something's a sandwich. It goes like this.
Name a sandwich and see if it makes sense to follow it with the word "sandwich." For example, today I ate a turkey club ... sandwich. That makes sense, thus a turkey club is a sandwich. If I said, "today I ate a hot dog sandwich," you'd wonder what I meant. I'd picture chopped up hot dog bits on bread with mustard, not a hot dog on a bun.
As comedian Esau McGraw said on "Why? with Hannibal Buress," a hot dog isn't a sandwich any more than a wrap is a burrito. Case closed.
