The Book of Culls

Have you ever been cut off in traffic? Or stepped in something that a dog owner has neglected to pick up? Or held a door open for someone, only to have them to breeze by you without so much as a nod of thanks?
What if you could vaporise those responsible so that it was as if they had never existed? "Human Cull" imagines just that.
People from all over the planet have sent in their cull suggestions for a little green alien to remove the really annoying people and leave the world a better place for the rest of us.
Who's annoying you most?
Cull them!
