In order to prove her P.E. teacher wrong (and to be around a guy she likes), Jane signs up for the track team, where she does very well and becomes a popular track star. However, she starts to find her friendship with Daria fading as a result of her new popularity.
The people of Lawndale just don't get Daria Morgendorffer. She's cool with that. See, Daria was born alienated, and now she's just trying to make it through high school with as little human contact as possible. Popularity, friends, activities... whatever. Daria lacks enthusiasm, but she makes up for it with sarcasm. Daria is the spin-off of MTV's most sucessful cartoon, Beavis and Butt-Head.
