How to Rock/Headscratchers

• I went to get glasses a few years ago and I got to choose what style I wore. Given all the styles of glasses to choose from, why would someone as concerned with her appearance as Kacey pick a pair that made her look so horrible?
  • Possibly because her prescription wouldn't fit anything but those frames, and also because it's a sight gag.
• For a show dedicated to how it is wrong to judge by appearances, why is the only character who is genuinely unnattractive (that fat ginger kid) demonized so much?
  • Rule of Funny definitely applies, and also, Andy (the kid's name) has already started to show up as a Breakout Character. Besides, he's one of he few characters in the show who is genuinely himself, and happy about it.
