As you stop at a motel for the night on holiday, you see a woman with a long brown coat, short-cut blonde hair tied up into a bun, and glasses over her eyes. You ask for a room for the night.

Certainly. Just sign in this book, I'll get you a key.

The woman turns around... and jumps down, revealing her to be a little girl standing on a stool as she goes over to a key rack... She looked like she was 6, but her voice was akin to that of a grown woman's.
