What I love about the episode "Quin the Brain" is when she puts on the outfit to look like Quin (as shown here), and shows that she obviously has curves but doesn't feel the need to show them off. This aspect of her makes the audience focus less on her gender and more on her character. For if she did show off her looks (because she does look as pretty, if not prettier than Quin in that shot), then she would be taken less seriously as an intellectual and become more of a sex symbol... Which she already is to some, but I don't get the whole "nerdy girls/guys are sexy" thing. At least in animation. In real-life, they can be very sexy (<-- is obviously dating one). But anyway, if you're wondering why I pointed this out it was out of sheer boredom and the fact it crossed my mind when I saw this collage.
