I wouldn't sail this ship if I were you
1. Think of a number, any number. Add four, and multiply by two. Subtract six. Divide by two. Subtract the number you started with. Now, what do you end up with?
2. There was a number that was caught in a maze, very like the one just constructed, and had to eat its way out. It was a dangerous process, costing an amateur mathematician three fingers and a chunk of thigh meat.
3. The mathematician was stitched up by a doctor at the tallest hospital in the world, which had just been constructed. It was twice as tall as any other building in the world, and one could look down from its upper floors at clouds passing by. All the staff at the hospital were new and none of them knew their way around.
4. The doctor got lost on his way home and had to sleep in a broom cupboard in the kidney department. He had a dream about being served a meal of purple food by a mysterious veiled woman. It would have been such a good dream, if only boiled beets, candied violets, red cabbage, blackcurrants, roast aubergines and plums had had some kind of joint flavour affinity.
5. The woman closed the door of the dream and took off her veil. Then she poled her boat along the river to the next dream she was contracted to appear in and put on a great cloak of peacock feathers. It was a dream for an aging judge, who was to be bent double in a box and whispered to.
6. The judge, however, was late for her dream, because it was snowing that night and the traffic around London had tied itself into a historic knot. It was the sort of knot that one gets in sewing thread, requiring only gentle pulling (or in this case, the movement of a single, unremarkable car) to undo. But nobody had the wider perspective to see this, so it remained in place all night until a squadron of police officers painstakingly cut and unravelled the thread elsewhere.
7. The road’s four lanes became a silent, black-and-white maze of snowy vehicles, navigated by blanket-wrapped figures. The driver of the car at the heart of the knot spent the night with twenty other drivers who had decamped to a nearby lorry with a heating system. They played cards all night and thought up increasingly ridiculous terms for snow. Hey, said the lorry driver, as dawn began to break. Think of a number.
