“The Black Clover Equation” by Zach Shephard, Flash Fiction Online April 2017, fantasy short story
This short-short takes a scientific (and hilarious) approach to lucky charms and their counterparts. (Given that approach and another element, it’s almost as much SF as fantasy.) The terse, dispassionate notes are appropriate for what they’re supposed to be but also create an almost Steven Wright delivery which makes it even funnier and the outrageous extension of the tale takes it to the finish line. (Although I think my favorite specific bit was the relatively modest black spray paint/combo effort.) Humor is in the funny bone of the beholder but I strongly recommend this.
