Re: Oh, lighten up already!
Love the pie approximation idea, that is utterly brilliant (although the corollary is that the interval in which you can eat an actual pie is infinitesimally short).
The Yank-bashing in this thread is just a bit of light-hearted nerdy banter, which - in this case - is richly deserved. First line of www.piday.org says: "Pi Day is celebrated on March 14th (3/14) around the world"
Get them to change that to in the USA and Belize and you might have a point :-)
Seriously, tho[ugh], American nerds should campaign for that date format to be abolished, just as European nerds should for DD/MM/YYYY: these formats are effectively ambiguous for 36.2% of the time!
