Clean And Tidy

The robot had its task, keep the property clean. And with its solar recharge station, it could, and did, do it indefinitely. When the paint flaked off the walls of the house, it cleaned them up. When the walls came down, it cleaned them up too.

As years became decades, the property stayed clean, tidy. Eventually humanity began to expand back towards the cities, and the robot was found.

The settlers tried to reprogram the robot, but just changed its parameters.

When the blood was shed, it cleaned it up. When the bodies piled up, it cleaned them up too.

Passing Judgement

He was one of the most prolific Adjudicators in history, and he was about to die.

For over fifty years, he served the crown by travelling the land and killing those accused of crimes. The Gods were known to exist, thus letting their infallible judgement determine innocence and guilt was the moral thing to do.

He was sure of it, and so when he died, he expected greetings and fast-tracked Heaven.

All he got was an endless sea of people, all of whom had been waiting to pass judgement on him for what he had done.

Most of it negative.

Cold

The storm lashed the windows, the house lights flickering on and off with every gust of wind.

Every time the darkness came back, he pulled a little away from the circle, content to let them drink and smoke. Soon he was alone, exploring this house all by himself. The coat rack gave him a fright, as did the kitchen door.

But then, accompanied by a crash of lightning, he heard a scream, cut off. He rushed back to the party, and they were all dead.

He realised none of them had worn a jacket just as the killer struck him.

The Dazed Postman Skit

There was always another stage, another audience.

He'd nailed down the act twenty years ago, and worked out every possible 'ad-lib' ten years ago.

It was a perfect act, never failed to bring the house down, it was his livelihood. He travelled the world on this sketch.

And then one day, he got a huge offer, a month"s worth of paychecks to perform the skit at the TV studio.

He did the performance, got great reviews, and went back to touring around.

But now there were no more stages or audiences, people has seen it now.

What else was on?

Shapeshifter Collector

It was a machine that appeared in various places, at various times, with various brightly colored signage.

Sometimes it offered a free beverage for a simple quiz. Sometimes it was a touchscreen only ATM. Every four years it was a voting booth.

It just moved about, collecting fingerprints, each one stored in non-powered memory banks. Looking, searching, seeking out one that matched the one in its ROM.

The A.I didn't know what would happen when it found them, that subroutine was hidden. It had hoped it could convey a message.

Instead it blew up, killing the shapeshifting alien using it.

John_Smith 2.0

It had taken decades to program, but John_Smith 2.0 was the end of money. Instead of relying on dumb pieces of metal, coin, or plastic to represent the concept of a unit of value, the computer network instead constantly calculated value and more importantly complex multi-stage bartering, wherein everyone traded at once, and society was improved, each to their ability and value, they could get what they wanted.

This worked well for a decade, until an all powerful being who could do anything with near zero energy entered the market and ruined it all for everyone via superhero causes hyperinflation.

The Old Witches' Cottage

The old witches' house wasn't actually anything to do with witches, it was just an old shack just on the edge between the village and the forest. No-one knew why it was called that, but what everyone knew but pretended they didn't was that it was where teenagers hung out, smoked a little, maybe fooled around. It kept them out of the way, and safe.

That is, until the day there was a party there, every teenager in town piled in, and then they all vanished.

They were last spotted near that nice clean cottage on the edge of town.
