Here at Puppet Pie (i.e. my house) we celebrate Pi Day with the essentials. Circles. Circles in the form of wheels, jar-lids, cupcakes, Samoa Girl Scout cookies, Ritz crackers, buttons, eyeballs, felt sticky-dots to go under the furniture so they don't scratch the new floors, spools of thread, and of course, chicken pot pie.
So happy Pi Day to you and your family. May a love of math known only to people who aren't me, find you on this splendid day.
