Every Welshman knows St David's Day, every Scot St Andrew's and every Irishman St Patrick's, but for some reason, we English mostly don't know that April 23 is St George's Day, and if we do, we don't make any fuss about it.
There are a lot of pubs called George and Dragon, and I remember a cartoon of a man knocking on the door of one such. The door is opened by a sour-looking woman. The man says simply "Morning, missus, is George in?"
I know it's not much of a tribute to St G, but it's the best I can come up with on a blazing hot Saturday afternoon.
