Lindsay Lohan reminds you that it's October 3 (thanks, 'Mean Girls')

Today, October 3, is a momentous occasion: It's when Aaron Samuels asked Cady Heron (Lindsay Lohan) what day it was in the seminal teen comedy "Mean Girls."

"I've been talking to Aaron more and more. On October 3rd, he asked me what day it was," Cady gushes. "It's October 3rd."

Okay, fine, it's not that historical of a day, but it's worth remembering nonetheless. Besides, who doesn't love "Mean Girls" and remembering when Lohan was a promising up-and-coming actress, not a tabloid trainwreck?

Even President Obama uses "Mean Girls" to remember what day it is -- or at least his social media team does.
