It’s October 3. #meangirls#itsoctober3rd,” Lohan (35), captioned a photo via Instagram of the iconic scene.

High school Aaron Samuels ( Jonathan Bennett), turned around to question Cady Heron, (Lohan), about the day. She explained that it was October 3rd. Cady treated the moment as a major event in their relationship and the insignificant exchange has been one of the most memorable scenes.

Bennett, 40, commented upon his former costar’s post using his famous line “What day?”

Amanda Seyfried played Karen Smith in the Tina Fey-penned comedy. She commented, “YES IT IS.”

Bennett, who hosted the Halloween Wars on Food Network, made numerous posts about this meme-able day. He captioned an Instagram Story video that he took in an airport, “And as I stood there on October 3rd I realized no other planet will ever understand how strange it is to be myself today.”

The Burn CookBook coauthor also shared video footage from The Christmas House 2, where Robert Buckley tried to recreate the famous moment with him. It’s difficult to recreate perfection.

Daniel Franzese shared a touching note via Instagram with several fan art pieces.

“Happy #MeanGirlsDay, I want to thank everyone of the fans for this movie that brings such joy and adventure into mine life,” the 43-year-old comedian shared . “Everyday I am more grateful for the follows, the dms, and the words that support my career and life. I am grateful for every one of your gasps and screams when I meet you or the tears that we share hearing your stories.

Franzese said, “Movies can heal.” Comedy can be especially healing. They were there to keep me going through my worst moments. My favourite movies contain the sounds of my closest friends and family laughing. Those movies are a living testament to those laughs. It’s obvious that you are basically fangirling over fan girls. Your fan art is amazing. Your talents amaze me every year. You make me feel valued and happy. Your support makes me want to do an amazing show for you. This is the day in a year that Mean Girls fans really pay attention to me. I just want to say THANK YOU SO MUCH. You are all truly special to me. #houseofglencoco
