This is bizarrely funny because me and my roommate Matt have lived with this guy named John for the past few months, and we occasionally throw out the question, "So, how are we killing John?" because he is such an awkward and creepy guy.
Sometimes he'll walk out of his room, stand in the doorway, and just watch us when we're on our laptops.

Also congrats Achiro you win at being a heartless human being.
