About a year ago, I posted a list of arXiv joke papers as an answer on Academia Stack Exchange. At the time, I was just going for a de facto “proof” that it’s okay to upload joke papers — after all, there have been so many of them, and some have been so famous, that if the arXiv moderators thought this was a problem they surely would have done something about it. (Which they haven’t.) But after the answer kind of exploded in popularity, I realized that (as far as I know) nobody else has bothered to list all these papers. So I’ve been keeping it updated each year.
And I’d be remiss not to mention this year’s entry, “Sitnikov in Westeros: How Celestial Mechanics finally explains why winter is coming in Game of Thrones”. This paper actually does have a real scientific explanation for the bizarre patterns of seasons in Game of Thrones.
