Guest Artist Week is the fourth story in chapter 28 of Sluggy Freelance, That Amazing Chapter with guest artist Jeffrey T. Darlington. Reakk accidentally destroys Lord Horribus' crystal unicorn collection, made from ground bones of real unicorns, and gets fired. He tries various other jobs with little success, and in frustration kicks a stone that kills a unicorn. The perfect opportunity, it would seem. Maybe Horribus' collection wasn't from real unicorns, though, but that's between us, isn't it?
