Continuity mistake: In the Season 1 episode "Too Cute," Quinn mentions to Sandy that Sandy picked out Quinn's outfit that she's wearing. This could not be possible as Quinn had that outfit (the same one she always wears in every episode) since BEFORE they moved to their current town and before the girls met anyone in their school they first went to in the first episode.
Continuity mistake: In the mall just before arriving at the doctor's office, Daria and Quinn walk by a business called "Butt Hut" and go fully past it, and then in a closer shot of the girls walking, they walk by "Butt Hut" again.
