I know, this topic does not fit that well here, but today is Pi day!  As I once studied mathematics, I am still very interested in these topics. Because this day is celebrated all over the world with funny activities and jokes, I hope some of you can get some fun out of it. At least it is a interesting topic at some cocktail parties 

See some jokes here:

Direct examples:

• What did pi say when someone asked if it could explain what Pi Day was again?
  "I don't want to repeat myself."

• Did you know that 3.14% of sailors are Pi-rates?
