 Once, a student lived in an attic while a grocer lived on the first floor with a "nisse", or house goblin.Because the grocer treated the "nisse" for Christmas with a dish of porridge () with a large lump of butter in the middle, the "nisse" was attached to the grocer.One day, the student came to buy cheese and candles; then he discovered that his cheese was wrapped in a page from a poetry book, so he bought the book instead of the cheese, and joked that the grocer knew nothing about poetry.
