That was to drive the point with a common reference point. The moon in this is comparing yourself with yourself. Maybe OP looks gorgeous with hair but banal wit

That was to drive the point with a common reference point. The moon in this is comparing yourself with yourself. Maybe OP looks gorgeous with hair but banal without and it's frustrating him. If shaving your hair gets you from an "8" to a "6" on a "hotness scale", that's two "points" wasted for nothing and OP may be looking at some quick win to get those two points back.
