"The man who invented the Total Perspective Vortex did so basically in order to annoy his wife.
Trin Tragula -for that was his name- was a dreamer, a thinker, a speculative philosopher or, as his wife would have it, an idiot.
And she'd nag him incessantly about the utterly inordinate amount of time he spent staring out into space, or mulling over the mechanics of safety pins, or doing spectrographic analyses of pieces of fairy cake.
'Have some sense of proportion!', she would say, sometimes as often as thirty-eight times in a single day.
And so he built the Total Perspective Vortex- just to show her.
And into one end he plugged the whole of reality as extrapolated from a piece of fairy cake, and into the other end he plugged his wife: so that when he turned it on she saw in one instant the whole infinity of creation and herself in relation to it.
To Thin Trigula's horror, the shock completely annihilated her brain; but to his satisfaction he realised that he had proved conclusively that if life is going to exist in a Universe of this size, then the one thing it can not afford to have is a sense of proportion."
