Knock

Count down for blast off. X minus 5, minus 4, minus 3, minus 2, X minus 1, fire. From the far horizons of the unknown, come transcribed tales of new dimensions in time and space. These are stories of the future. Adventures in which you'll live in a million could be years on a thousand would-be worlds.

The National Broadcasting Company presents... One... Tonight, the science fiction classic... Knock...by Frederick Brown. Tonight we have a strange story to tell. A sweet blood-curdling story that is only two sentences long.

The Last Man on Earth sat alone in a room, there was a knock at the door. What's that? Man. What? Who are you?

You have regained consciousness. Who are you? I am Zann. I'm still asleep, I must be. You are not asleep. Maybe if I close my eyes it will go away. I will not go away, man.

No. I guess I'm awake. What are you? I am a Zann. What's that? A Zann is intelligent life. Look, I don't... What happened? Where are you from? From planet seven in the third galaxy in the fourth quadrant.

It is not necessary to repeat information which is correct in the original statement. Planet 7, but you mean I'm not on Earth? You are still on your planet. And what are you doing here? The Zans have annexed your world.

You mean you conquered Earth? Yes, that is correct. We will now prepare your planet for habitation by the Zans. How about the people? What about the population of the world? You are the population of the world.

Now wait a minute, I can't... I don't understand what's happened. The zan have landed on your planet. We have removed the lower life forms to repair for colonization by the zan. When did all this happen?
