Do you like your hot dog to be the same size as your bun?
Or, do you prefer your hot dog to be longer than its bun?
Personally, I'm in the latter camp. I want a few bites of my hot dog sans accoutrements.
When the dog protrudes out from its given bun, I can take a few bites of just dog (no bun, no mustard, no ketchup, no nothin') and savor for a few moments the sausage I'm ingesting.
Naked is the best way to size up a hot dog, figure out if it's a real frank or simply an imposter using all those condiments and toppings as a crutch.
