Not even the whole of the UK - really only England and Wales (as a singular entity, rather than individually).

The rest of us know it only for its impenetrable jargon ("They've risked a woggle on the silly midden!"), the grating public school chumminess of the commentators, and a rumour about a puerile "joke" which may or may not have been told on the radio coverage in the early 1980s.

Honestly, it's a sport I suspect I ought to like - full of stats and strategy - but it really does seem impossible to follow unless you've been inculcated since birth.
