This made me smile:

You can divide most sports into those that take place in the real world (road cycling, sailing, cross country running) and those that are played on the artificial space of a court or pitch. Some (golf, croquet) occupy an uncertain middle ground, which may be one of the reasons they are so tedious to watch. Others (football, rugby) started as the former and, as they were codified, became the latter.
