Saturday 03-14-15 (why does that sound so familiar?) is a very rare and special Pi Day
, b/c the date spells out the first 5 digits of Pi.
This won't happen again until 2115.
Celebrate with your fav flavor of pi.
In observance of this special occasion, here is a pi joke;
Father (to his son home from school): What'd ye larn t'day, sonny?
Son: Pi r square!
Father: Fool kid. Pi are not square, pi are round.
