I'm in a random mood, so here are random pi facts:
Inscribe a circle within a square. Choose random points within the square. As the number of points approaches infinity, the number of points that fall within the circle divided by the total number of points, times four, is pi. http://mathfaculty.fullerton.edu/mathews//n2003/montecarlopi...
Memorizing something like the first 8 digits of pi is enough to calculate the circumference of the Earth to within a few inches, iirc. (My memory is bad, so it's probably 8 +/- 2 digits.)

The quadrillionth bit of pi is zero. http://www.daemonology.net/papers/
And keeping in spirit with the post, here's a pi chant: http://pi.ytmnd.com/
