Irrational

Today is Pi Day. Really. Therefore, could there be a more perfect day to make a pie? Not if homophones count in observing the mathematical holiday.

I made a peanut butter pie.

I get the idea for March 14 being Pi Day because here we list month, day, and year, but does this make sense in those countries--I'm looking at you, Europe--where it goes day, month, year?
