Plot hole: Throughout the series, Sandy always refers to Daria as "Quinn's cousin" or "that girl that lives with Quinn" or other random titles for Daria (not knowing that Daria is Quinn's sister). Although Quinn admits to Sandy that Daria is really her sister in one of the last episodes of the final season, in this first episode of the series, Sandy is in the crowd watching Daria give a speech and Daria reveals to everyone Quinn is her sister (embarrassing Quinn). Sandy should already know they're sisters.

Continuity mistake: When Mr. O'Neill is talking to Daria and Jane, the board behind him has a bunch of arrows in a circle with a different word written next to each arrow. When the camera changes to a further angle with all three characters in the frame, the arrows remain on the board but all the words are completely gone - then appear again once the camera is close up to the board again.
Continuity mistake: In this episode, during the party, we see Tiffani (from the fashion club) for the first time, and when she speaks (just once in the episode), her voice is extremely different than the low monotone voice she has in later episodes. Here she sounds more Americanized and has a higher-sounding voice (similar to Stacy's).
Continuity mistake: As Jody is shown up close talking in the classroom, her hair (usually black) looks dark grey in this shot - then after a camera angle change with her further out, suddenly her hair is black once again.
Continuity mistake: When Daria and Kevin are talking in front of the lockers early in the episode, the lockers don't have any numbers on them like they normally do in other episodes.
Continuity mistake: The blackboard behind O'Neil has a face drawn on it with tears coming down on each side of the face. In some camera angles, three tears on each side are shown, and in other camera angles, only two are shown. This number of tears keeps alternating.
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.
Continuity mistake: The two tablets that Helen made both first have the word "RULES" printed on the top, but in a later scene, one of the tablets says "CONT" on the top, and Daria then pushes it over, and we see the backside of that tablet completely blank. This is not possible as both tablets had the word "RULES", so seeing each side of one tablet without that word on it doesn't make sense.
Revealing mistake: When the fashion club is looking at clothes in the store, Quinn and Stacy are looking in the mirror and their reflections properly show. When a slightly further angle is shown including Sandy (who stands right next to Quinn), Sandy's reflection does not show in the mirror at all (even though she's standing right by it). Also, no reflections are shown of any scenery in the store or the other two girls (who are within reflection range) - again, just Quinn and Stacy are reflected.
Continuity mistake: When Daria first hops in the van, she bangs the top of her head on the wall of the door getting in, but later, when the bruise is shown from the incident, it is now on her lower forehead (just above her eyes). The bruise would have been much higher up according to where she first hit her head.
Audio problem: When Trent is playing the guitar for Daria outside, he plays a "G" chord several times. Right after telling her it's a "G" chord, he plays it again, then switches his hand on the strings to a completely different area and strums (which should play a whole different sounding chord), but we still hear the same "G" as if he didn't move his hand on the strings at all.
Answer: "Mack Daddy" was a 90s phrase meaning "Ladies man," and Mack simply doesn't like the stupid nickname.
