The elusive slogan glows in the dark blue night of the first episode of FLCL.
What does it mean? Or what does it mean to Mamimi who has presumably scrawled "NEVER KNOWS BEST" along the length of her cigarette, and burns the message down as she takes it into her chest? Does Never Knows Best even mean anything, in a series where the title itself is invented nonsense and the cast openly questions its definition?
Never Knows Best isn't even a proper sentence, is it?
It is instead, beyond meaning, perfect as the crowning contribution to the perfect moment. That moment is about being a disaffected 17-year-old standing in the middle of a bridge in the middle of the night, stalled halfway between noplace and notgoinganywhere. She pines for her never-seen, long gone baseball-playing ex, tries to replace the absent boyfriend with his 12-year-old brother, stray cats and strange new robot gods, and in this moment is just utterly convinced that she is lost and broken. The tobacco embers connect with and forecast Mamimi's eventual pyromania, and eventually, eventually maybe (maybe) she'll get over all this and be okay.
But in this moment there is one perfect, cryptic, bleak-sounding, moody adolescent thing to write on a rumpled cigarette.
It burns all the way down,
fire to air to water,
never knows best.
Ah! Sweet mystery of life!
