I've always been partial to "Rachael"...

The vague and indistinct person becomes a little more defined. Definitely female, but the body type is changing and shifting so fast she looks like every woman at once, yet like none of them.

"Rachael, eh? am I a nice Jewish girl?" she asks. "In this multicultural world, with a name like Rachel, I could still be almost anyone, really. Let's get to defining this. You're a writer, write something."

Yep, you're definitely a nice Jewish girl. Wavy light brown hair, green eyes, good cheekbones. Hey, I'm not gonna write an unattracive chick, so no worries about the nose, okay? it fits your heritage and definitely belongs on a pretty face. Strong jaw and chin, without being manly, and a wide, thick-lipped smile. There we go, gotcha defined from the neck up at least. Time to let someone else play a bit; I'll be back with my own when I can.
