"I'm drawing something for you, Daddy, and you have to guess. It begins with 'one'."

My four year-old son scribbles furiously on a magnetic sketch pad, then shows me his picture. It looks like a man, in preschool lollipop style, with oustretched arms and squiggly hair. Lots of lines radiate around the arms.
I try to think of any name that begins with 1. I'm mentally browsing Star Wars droid names when my son puts me out of my misery.

"Wonder Woman!"
