'Mean Girls' Flashback Chat with Tina Fey (WATCH)

"Sometimes older people make jokes too." It's been 10 years since Cady Heron (Lindsay Lohan) first hit the halls of North Shore High School, and in honor of this "totally fetch" day, let's flashback to Mean Girls writer and star Tina Fey's first ET interview about the 2004 movie.

The 43-year-old funny lady adapted the book-turned-movie and also starred as teacher Ms. Norbury in the beloved teen comedy.

"I had been wanting to try to learn how to write a movie. I had been looking for a subject matter for me for a couple of years," the 30 Rock star told ET back in 2004. "When I got this book, Queen Bees and Wannebes, which is the book that the movie is loosely based on, this is the first time I thought, 'Oh here's this topic, it's really kind of juicy, and it's funny. Maybe this will be the one to try.'"

As for her high school self, Fey claims she was "never good looking or well-dressed enough to be a Plastic."

"There were girls in my school that were like that though, who were just sort of famous, and you just knew everything about them," she recalled. "They just had really good hair and they had nice clothes and you felt like they knew some kind of secret of how to do it."

She added, "I was just a greasy-faced, sweaty goon in high school."
