Ya know guys, I'm thinkin' maybe the whole reason this here "St. George Day" thing hasn't ever caught the British public's fancy is 'cause maybe it's a little too, lets say, religious based.
Uh huh! Ya see, I think what you guys need is somethin' a little more secular in nature!
And so, here's my suggestion:
Why don't you guys set aside July 5th to celebrate! Yeah! Ya see, you guys could call it somethin' like, "We're No Longer Responsible For What Those Damn Yanks Do Anymore Day"!

(...of course, if you think about it, you guys should've been celebratin' this day for over 200 and some years now!!!)
