I Am Not Sidney Poitier by Percival Everett:
At the other end of the weapon was a singularly ugly redheaded boy of perhaps twelve years. I had never thought a child could be ugly, but his mouth was too small for his pie face, and yet his teeth were those of a larger person. All this set below a nose out of something by Erskine Caldwell. And all that on a head far too large for his scrawny body. Even with the gun pointed at me I wondered immediately how I could take in so many features so quickly and wondered further if he could close those lips over his bathroom-tile teeth.
