This article seems to have been stimulated by the sort of thought I occasionally have while using the bathroom. Thinking "there are three urinals in here. There are two bathrooms on each floor. There are five floors in the building..." Then my urinal-consciousness expands to all the other buildings in the area, and all the urinals they must contain. Then I think of how many there must be in the country. And how many valves and other plumbing. And how many rolls of toilet paper. It kinda blows your mind how much stuff there is.
