Tomorrow is Pi day! No, not the Japanese syllable, but the math symbol!
Pi, for those who don't know, is roughly equal to 22 divided by 7 [3.14159....] and continues infinitely.
Tomorrow [or today, if you don't read this till the 14th] is the holiday that celebrates that particular number! [3rd month, 14th day]
I know what you're wondering, "How can I celebrate this most awesome of holidays?" Well, that's very simple! You could eat massive amounts of pie [try and beat the record I just set at my school - 11 pieces of pie, and 2 pieces of pizza in 20 minutes], you could decorate your living space [or yourself] with the image of Pi! Anything!
