If you're a mathlete, you know that Mar. 14, is a very special day. It's Pi Day! For those of you who don't know, however, about the celebration-worthy date of 3.14 (or if you're like me and thought Pi day was actually Pie day), seriously don't feel bad — you're not alone, and I'll explain.

Pi is the ratio of a circle's circumference (distance all the way around) to its diameter (distance from side to side) — and it's a constant number that will remain the same in any circle of any size. This is because while circles can obviously vary in size, they don't vary in shape — that's what makes them all circles — their shape! So for any circle, dividing its circumference by its diameter, will give you the same number: 3.14159..., aka Pi. Because we like to round numbers, though, Pi is most commonly referred to as 3.14 — which looks a lot like Mar. 14, hence its celebratory origins (which go all the way back to 1988, when physicist Larry Shaw founded the "holiday." Thanks Larry!)

To celebrate, people eat pies. Because, what else is there to do? And while the two words are merely homonyms and have no relation to each other (even though pies are round) observers of the holiday are happy to appoint the sweet as celebration must-have. But perhaps the best part of Pi day are not the pies, it's the memes that surface on the interwebs. To show my festivity for the holiday that honestly just gives me flashbacks from flunking math in high school, I offer you humorous memes. Because math can be funny, especially if the internet gets to it.

## Gotta Get Down On

The Rebecca Black song that just keeps on giving. Seriously, who knew this song would be so handy?

## Math Life

A harsh, but potentially honest reality.

## Totally Irrational

Honestly, I had to look this up. Pi cannot be expressed as a fraction, which mathematically speaking, means that it's "irrational."

## OK, True

Even I get this! Pi never ends! It goes on forever!

## Hey Girl

Why didn't Ryan Gosling actually think of this one? Epic.

## Magic Or A Coincidence?

Funny how these things happen. Who figured this one out?

## Mathlete's In Trouble

One serious mathlete came up with this one.

## Get It? Pi Goes On Forever

Poor pi.

## He's Been Waiting For This Moment

Right though? Whoever did this was probably waiting for this moment for their whole lives. And what are the chances it will ever happen again?!
