Whether you're a mathlete, a foodie, or just a general national holiday buff, you know that Thursday, Mar. 14, is a very special day, because it's Pi Day! To celebrate, you'll want to cut yourself a slice of actual pie, and gear up for some epic social media posts. To help, I've put together a list of funny Pi Day Instagram captions, because honestly it can be hard to be witty and clever when it comes to numbers or food. Funny quotes in lieu of captions is definitely the way to go. But, if you'd like a refresher on WTF Pi Day is, I don't blame you, the delicious and mathematically holiday can be confusing. Here's what you need to know.

In math, Pi is the ratio of a circle's circumference to its diameter — it's a constant number that will remain the same in any circle of any size. When you divide any circle's circumference by its diameter, you will get the the same number: 3.14159..., aka Pi, most commonly known as 3.14 because we round down long numbers like that for simplicity. As you know, Mar. 14 can also be represented as 3.14, which is how the holiday came into existence. In 1988, physicist Larry Shaw founded the holiday, and the rest is history. Literally.

In food, pie is a homonym for pi. So it didn't take long for lovers of the sweet treat to decide to merge the math reference and the dessert together into one epic day. Personally, I like to look at it as a choose your own adventure kind of holiday. As someone who's still scarred from high school math, I take the pie route and indulge in baked goods. No matter how you choose to celebrate, you'll want a great quote to go along with your Instagram post. Here's a combination of profound math concepts and sweet odes to everyone's dessert of choice.
