Posthuset (building)
Postgirobygget is a 110 meter high building in Oslo, Norway. The building serves, among other things, as the home office to Posten Norge, the Norwegian postal service.
Modern advances in the field of Aesthetic Pattern Theory and Objective Sensory Verity Analysis has made it possible to prove mathematically that this is the ugliest object ever conceived, not only on earth, but on every possible planet in every possible universe. This is not scientific theory, it is a mathematical fact. It was the very famous Norwegian scientist Ari Behn who in 2003 discovered what is now known as the Light Fountain Principle, which shows that there is an inverse relationship between an object's geometric similarity to Postgirobygget and it's aesthetic value. In other words: As an object's geometry approaches that of Postgirobygget, it's hideousness approaches infinity (no citation needed, just look at the picture).
