From Wikipedia: Nuggan is the locally worshipped monotheistic and omnipotent God of Borogravia, but elsewhere he is known as the God of Paperclips, Correct Things in the Right Place in Small Desk Stationery Sets, and Unnecessary Paperwork. His holy writ (the Book of Nuggan) is a Living Testament, into which more material is added on a regular basis. All believers regularly add pages to the ring binder Appendices, which then eventually fill with more commandments, usually Abominations unto Nuggan. Among his ever-growing list of Abominations are cats, the colour blue, Dwarfs, oysters, mushrooms, chocolate, garlic, babies, cheese, the smell of beets, ears, jigsaw puzzles, and rocks. He is now dead because belief has switched to his abominations, rather than the god himself.
Small Print: Nuggan is a creation of Terry Pratchett in the Discworld universe. I am in no way affiliated with Terry Pratchett, except as a fan. You should read the book Monstrous Regiment for more background on Nuggan. In fact, you should buy and read all of Terry Pratchett's books. What are you waiting for?! Illiteracy is an Abomination unto Nuggan!
