"On October 3rd, he asked me what day it was...It's October 3rd."

Those who know and appreciate the iconic 2004 chick flick, Mean Girls, understand the significance of October 3rd. If you're a true Mean Girls fan, here are some great ways to celebrate the day-- or heck, make it the whole week-- that Aaron Samuels first spoke to Cady Heron in calculus class.

1. Watch the movie in its entirety.

If you're like me, you'll be able to quote every single line without a problem. Watch it with friends, but warn them that you'll probably be imitating the each of the characters throughout the whole movie. It truly never gets old.

2. Make some fun "unalcoholic" drinks.

Just like Regina's mom! "Is there alcohol in this? Of course not honey, what kind of mom do you think I am?"

3. Send some candy grams to your friends.

"Four for you Glen Coco, you go Glen Coco! Aaannnnddd none for Gretchen Weiners, bye!" That'll be sure to make them as jealous as Brutus was of Caesar.

4. Carb load.

Maybe pick up some Kalteen bars? Or maybe pay a visit to Karen's personal favorite, Taco Bell?

5. Learn the Jingle Bell Rock dance.

I mean, Regina got hit by the bus and has a spinal injury, so someone's going to have to fill in for her next time around.

6. Practice some calculus.

All you've got to know is that the limit does not exist, though.

7. And finally, please WEAR PINK.

Because we all know that if not, you can't sit with us.

Though a Mean Girls fan might practice these habits only once a year on the beloved October 3rd, true Mean Girls fans are in pink every Wednesday for the rest of their life.
