Although Regina George (Rachel McAdams), Karen Smith (Amanda Seyfried), Gretchen Wieners (Lacy Charbert) and Cady Heron (Lindsay Lohan) only wore pink on Wednesdays, the infamous Plastics from the 2004 cult film “Mean Girls” would most likely make an exception to their color rule this Monday to honor "Mean Girls" Day. The holiday celebrates the day Lohan’s character Cady was asked a very important question on Oct. 3 by her crush Aaron Samuels (Johnathan Bennett): “What day is it?”
