Halal Pi

When the digits of the number π used in a given calculation to a certain degree of accuracy to produce a product need to be checked and approved by certified Islamist or Mohammedan educators before it could be sold to green customers.

The Taliban warn green publishers that only math titles that have the “halal pi” stamp on them could be used in local universities.

PI

PI is short for the Philippine Islands. Philippine Islands is the old name of the Republic of the Philippines. The Philippines was formerly known as Las Islas Filipinas, named after King Felipe II of Spain, when it was a colony of Spain from 1565 to 1898. Then it was Anglicized and it became known as the Philippine Islands when it became a U.S. territory shortly after the Spanish-American War of 1898. In 1946, upon independence from the U.S., it became a republic. The name of the country was then changed to the Republic of the Philippines.

Yo, I’m going back to the PI next year.
