This was simplified to "You are what you eat" as part of the agreement reached at the Council of Constance to reunify the church after the Western Schism of 1378.
That always bothered me, sausages are naturally silly, first we shoved the ground up and spiced meat of the animal into its own intestines, then we make it into phallic shapes, then when we cook them they jump around and scream like tiny little limbless people.
That's why Frankfurts have a German name, they're serious and convenient.
I like the idea of hot dogs more than I actually like hot dogs. Every now and then I get a craving for one and throw it on the grill but it's always slightly disappointing. It's never as good as I think it'll be. I need to learn to just stick with hamburgers. Those are never disappointing.
Before you put them on the grill, slice them about half way through diagonally on one side and diagonally again in the other side in the same way ... the hot dog will expand across the entire length and crisp along the cut edges. More crisp makes it taste better and the longer length actually fits the length of your bun.
Just to be a pedant - most hotdogs (or indeed any sausage) haven't used actual intestine for some time now, they generally use a manufactured collagen casing.
