Of All The People That Won't Be Missed
Of All The People That Won't Be Missed is a crossover between the film Natural Born Killers and Daria & Beavis and Butt-head by LongSnakeMoan. The role of mass-murdering couple Micky and Mallory Knox are taken by Todd Ianuzzi and Jane Lane, around the time of "Is It Fall Yet?". (Due to violence and language, this is an 'R-rated' fic)
As Jane and Todd cut a bloody swathe through America and get increasingly closer, they also become the darlings of the country's mass media and youth culture, while Daria waits for the inevitable moment when they come back for her.
After readers began 'replying' to the fic with in-universe character tweets, LongSnakeMoan began to weave them into the fic (making it a shared world): what readers had the characters tweet would become part of the story and Todd and Jane would tweet back, leaving comments, taunts, and threats.
