Did you know that there is author known as 26 pages? Or, meet author A. Or D and B. Do you think LaTeX is a first name or a last name? Author Development Center, Japan, and 210 all appear in one paper.
Among abstracts, there are some fun ones, including verses from the Bible (arXiv:0912.1053):
“And should I not take pity on Nineveh, that great city, with more than a hundred and twenty thousand inhabitants who do not know their right hand from their left, and many beasts besides?” [Jonah 4:11]
Here is an abstract which contains optional and mandatory headings.
Titles? Well Holey Sheet! I did know that 6+4=10, but am not sure what to do with the fraction 27/32, even though I know one of the authors. Among my favorite titles is “Is topological Skyrme Model consistent with the Satandard Model?”
I also enjoy the comments where they admit the paper wasn’t so good: “withdrawn. It was a rediculously stupid notion”.
Some papers also tread in directions I never would have considered. For example, The Socceral Force is about a strange dream and describes a little known markup language, Footballer and Football Simulation Markup Language or FerSML.
