A 2004 essay by CF, updated several times until 2008. CF did a deep dive on various episodes of Beavis and Butt-head, to examine the development of Daria's character and what Daria fans can learn about her via the original show.
At the original time of writing, there was no in-print home media of Beavis and Butt-head and even after, uploads of the unreleased episodes would be hard to get: fans relied on this for information. (The essay also uses the edited-to-remove-fire version of "Scientific Stuff" available to them at the time)
It was the winner of "Favorite Non-Fiction Essay" in the 1st Daria Fanworks Awards
