Happy PI Day

Someone wished me Happy PI Day today, I thought it was P.I. (Private Investigator) Day.
 PI is good, I like pie and I actually remember that pi is 3.14.                                            
 DYK -  there is a pi day website?   http://www.piday.org/
Anyway, Happy PI Day and thanks to Supersonic Safety Research's friend and colleague LI PI for wishing us a Happy PI Day.
