It's Pi Day, Pi Day: How To Celebrate?

From the wikiHow:

Celebrated on March 14 at 1:59pm, Pi Day is a special day in the lives of many people devoted to Pi. In much the same way that people celebrate Daylight's savings. People around the world gather in the shape whose ratio of its circumference to its diameter is the most revered mathematical constant in the known universe. If you're keen to become a part of the Pi Day celebrations, just follow the steps for making this day memorable to one and all.

1. In case you're not aware, note that Pi Day is held on March 14 because the date is 3.14. Pi Approximation Day is held on July 22, because when using DD/MM format, it is shown as 22/7, the fraction for pi.
2. Create some pi ambiance. Just as people display a tree and mistletoe, wear Christmas gear, and sing Christmas songs around Christmas, there is a lot of room for making the environment around you reminiscent of pi.
3. Convert things into pi. This step is absolutely necessary for two reasons: To utterly confuse people who have no idea what you're talking about (thus opening the door for enlightenment) and to have fun seeing how many things can be referenced with pi.
4. Play pi games and make strange mathematical endeavors. These are in the same step because many math nerds consider them the same thing. There are plenty of traditional games that are appropriate on Pi Day, like a pinata, a pie-eating contest or pie-in-the-face fundraiser, etc.
5. Eat 'pi' foods. Many creative ways exist to do this.  
6. Do a pi mile run. Go on a run for pi miles. You can take this a step further by organizing a pi mile run with friends or colleagues.
7. Watch the movie π. It's a dark movie about a mathematician who goes crazy. But it's way good, just not one for the kiddies though.
8. Listen to Kate Bush. Progressive rock musician Kate Bush performed a song titled π on her 2005 album Aerial. Bush sings pi to its 137th decimal place, but omits the 79th through 100th decimal places of pi for currently unknown reasons. Playing π on Pi Day, therefore, is left to the discretion of the celebrant. Just watch out for party-crashers playing Zero by Smashing Pumpkins.
9. Help the tradition continue. Don't let this be a one time thing–you owe it to pi to celebrate again and again. Set the date for next year and maybe create a pi club or website in the process. Celebrating Pi Day is just as easy as pi (sigh).
10. Get married on Pi Day. There's nothing more romantic than being married to the one you love at 1:59:26 PM on March 14th to show that, like Pi, your love will continue forever...
