Jeff the Killer and Johnny the Homicidal Maniac by
InsanelyA.D.D reviews
Essentially this is the written version of my fan/webcomic series Jeffy and Johnny, which you can find by looking up my name on DA, if you think the chapter sizes are too daunting, or are interested in seeing the more visual version of it. ALSO: Creature Feature, more CreepyPastas, Invader ZIM, Welcome to Nightvale, MLP, and far more in future chapters. Pretty much a comedy.

Five Nights with Mr C by
RiddledRose reviews
On the way home from his holiday, Nny finds himself stranded in a small town when the engine of his car dies out. He doesn't have enough money to pay for its repair, but thankfully a goofy oldster in a gaudy orange suit has offered to cover the cost if Nny agrees to look after his business for him after hours. Nothing bad could possibly come from that...right?
