What are your favourite one-shots (any genre; NO porn without plots though)?

I am bored as hell and choosing to ignore the absolute unit of a mountain that is my want to read list, so I want some one-shot recommendations.

It can be any genre (for example action, psychological, comedy, etc.), if you're recommending a romance it can be any pairing (ie. straight, BL, GL), BUT PLEASE DON'T RECOMMEND ANY PORN WITHOUT PLOT STORIES. Also I hate reading doujinshis (the shipping kind [SatoSugu, FarCille, uhmm idk any straight ships but I think you get what I mean, yeah?]) so none of those either, please.
