Pi Day: Geek Out Hard on 3.14! >>Hollywood

Pi Day is here again! You know, March 14? 3/14? Get it?!

For those of us who aren't irrationally interested in numbers, Pi is named after a mathematical constant - the ratio of a circle's circumference to its diameter.

While usually rounded to 3.14, Pi is not a finite number. In actuality it is 22/7, which has been calculated to a million-plus digits. It is LITERALLY never-ending.

Here are some ways to mark this special occasion:

• Bake yourself a Pumpkin Pi. It's funny and probably tastes awesome.
• Wish everyone a happy Pi Day just to see if anyone actually gets it.
• Hold a moment of silence at 1:59:26 p.m. today (Pi = 3.1415926).
• Celebrate Albert Einstein's birthday ... sort of appropriate, right?
• Get down to the Pi rap below (obviously someone made one)!
