KatiePie:
Well it is called the English vice but there seem to be a lot of Americans (and a few Swedes) on here who share that vice.
Having a spare month recently, I did some research. Using Library stats and a world population website, I calculated the LSF membership rates for different countries. The results (to the nearest hundred) bear out the legitimacy of the English claim to (some kind of) ownership of this our 'vice':
Leadership Board:
England 1 in every 18,100 (i.e. chances are 4 of us are at Old Trafford for home games)
Scotland 18,600
Wales 22,400
Ireland 30,700
USA 31,900
(UK as a whole = 1 in every 19,100)
The top non-English-speaking countries are:
Iceland 1 in every 42,700
Denmark 47,900
Sweden 54,000
Norway 54,200
Netherlands 92,100
(This may say more about these populations' language skills than their spankomania.)
