  • Call 314-1592 and see if someone picks up!

  • Carve Pi into a pie and than eat it!(How does the pi symbol look like? Go to my other post called "pi digits and symbol")
  • Have everyone to recite all their pi digits and the person with the most wins a pie!
  • Visit Savannah, Georgia because its zip code is 31415.
  • Ask a mailman in Savannah, Georgia "What is the zip code?", and see if he/she knows it!

  • Ask people how dare them to round the 5 to a 6!(3.1416!)
