"I don't know why you are. I don't know what you want. If you are looking for a web page, I can tell you I don't have it.
But what I do have is a particular set of error pages; error pages I have acquired over a very long career. Error pages that make me a nightmare for people like you.
If you return to the previous page, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will kill you."
