One of the most useful inventions ever is the sign. One of the most useful uses of the sign is to warn people who are either unstable on their feet, or just moving around too fast for their own good, that they are entering an area where a solid tiled floor has recently been covered in water, either through accident or the cleaning process. This is so that they can take extra care not to fall over.
However, the thought occurs that it has been known for people in a crowded area to fall over the signs themselves, for they are placed strategically in the middle of the floor, and being only a foot or two in height, it is not difficult for them to be completely obscured by peoples’ legs.
One wonders why there are not signs saying “Caution. ‘Caution. Wet floor.’ sign.” Of course, by induction this would mean that you would then need a sign saying “Caution. ‘Caution. ‘Caution. Wet floor sign.’ sign.’ sign.” and so on, until the world is totally covered in signs saying “Caution. Caution. Caution…. Caution. Wet floor sign. sign. sign…. sign.”
Or the signs could just be 7 foot tall.
