Despite all that (or since of all that), there are means of using this trope devoid of falling into that pitfall. Twilight Sparkle is Cute Bookworm extraordinaire and the Only Sane Mare in Ponyville most of the time, but several episodes showed that she can be extra unstable and perilous than the relaxation of the main cast combined, with one particular scene from "Lesson Zero" getting the trope to an art variety.
