He was clearly a man of many qualities, even if they were mostly bad ones. - Douglas Adams

It is an important and popular fact that things are not always what they seem. For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much, the wheel, New York, wars and so on - whilst all the dolphins had ever done was muck about in the water having a good time.

"Share and Enjoy' is the company motto of the hugely successful Sirius Cybernetics Corporation Complaints Division, which now covers the major land masses of three medium-sized planets and is the only part of the Corporation to have shown a consistent profit in recent years.
The motto stands — or rather stood — in three mile high illuminated letters near the Complaints Department spaceport on Eadrax. Unfortunately its weight was such that shortly after it was erected, the ground beneath the letters caved in and they dropped for nearly half their length through the offices of many talented young Complaints executives — now deceased.
The protruding upper halves of the letters now appear, in the local language, to read "Go stick your head in a pig," and are no longer illuminated, except at times of special celebration."

If the Universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don't. It's like a human body, you see. A few cuts and bruises here and there don't hurt it. Not even major surgery if it's done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make.
