For us non mathmeticians, we like to celebrate PIE day. My youngest daughter LOVES Pie day. One of her favorite things to do as a younger child was to tell random strangers, "I like pie." I have a pre made Keebler crust and a couple boxes of chocolate pudding. I think I might pick up a container of cool whip and make a pudding pie.
If you want to celebrate Pi or Pie, have a happy Pi/Pie day.
