(from Pi Day, 2012)

Confession: When I first heard about 'pi day', I did not understand the purpose.  
A friend of mine -- a math teacher -- had gone to the bakery to buy apple and cherry pies to bring to class the next day. ..  Why was she having a party?
She commented, "It's Pi(e) day. We have pie and talk about circles and their characteristics."
The next day at work, I looked at a digital calendar and saw  3.14...  March 14th!  Then, I understood!
Below is a comic about Pi(e) Day!
