Yes, it could be quite a day.
If Ireland win with a bonus point and England don't, then Ireland will be champions and would go to Twickenham to try to secure the grand slam and triple crown - oh, and retain win the Millennium Trophy too.
It would be nice for me if I were to find myself driving back from my mate's house, having watched Villa hammer Wolves whilst at the same time knowing that Ireland had earlier run in four tries against Scotland, and that England had had to be content with a three try win in Paris.
Of course, Scotland are not coming to Lansdowne Road to make up the numbers, it's not unlkely that I'll have to watch the football game from behind the couch, and our Gallic friends might fold up their tents when the roast beefs come to town.
And even if it turns out that I'll go to sleep with a smile flickering round my lips, I cannot imagine England not wanting to spoil the St Patrick's Day party in London,
