The Marmalade Sandwich Principle was devised by a man named Jonathan Brown. It revolves around the fact that, since all things are made out of the same thing (atoms), then all things must be the same. This principle is renowned around the world and has stemmed many scientific branches and even religions based around it. It is not known why the principle has named as such but it has been speculated that it involves certain family ties to Mr. Brown. It is one of the main factors in Trashology.
