How I wish I could enumerate pi easily, since all these horrible mnemonics prevent recalling any of pi's sequence more simply.
(Seen here.)

It was Pie Sunday (the second Sunday of each month) at my church today -- 3.14.10! Even I got that one!

On Pi Day I stumbled across Pilish, which is a kind of constrained writing for poetry. In a Pilish poem, the number of letters in each successive word matches the successive digits of pi. For example:(3 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 2 3 8 4 6)

Interesting! Shouldn't the first word be a one-word sentence--for the decimal?

As our calendar only has 12 months, we don't get to celebrate Pi Day in Australia.

I used to scoff at Pi Approximation Day. "Twenty-two sevenths?", I'd laugh, while twirling my mustache. "Don't make me laugh!"
It has since been pointed out to me, though, that "3.14", without any subsequent digits, is actually farther from the true value of pi than 22/7 is. This means that we are the approximators, and you guys who celebrate in July are much closer to the Platonic form of pi.
Boy, do I feel sheepish.
