“The shortest horror story:The last man on Earth sat alone in a room. There was a knock on the door.”

“There is a sweet little horror story that is only two sentences long: 'The last man on Earth sat along in a room. There was a knock at the door…'Two sentences and an ellipsis of three dots. The horror, of course, isn't in the story at all; it's in the ellipsis, the implication: what knocked at the door. Faced with the unknown, the human mind supplies something vaguely horrible.”

“I wonder if rooms in an insane asylum have Do Not Disturb signs for the doors. I should hope not, because knock or no knock, every occupant in those rooms is already disturbed.”

“You can knock on a deaf man's door forever.”

“I go to bed and then that man sits in the next room and continues laughing about his own writing. And then I knock at the door, and I say, now Jim, stop writing or stop laughing.”

“Any man who knocks on the door of a brothel is looking for God.”
