Finding one of her students making faces at others on the
 playground, Ms. Smith stopped to gently reprove the child.
 
 Smiling sweetly, the Sunday School teacher said, "Johnny, when I
 was a child, I was told that if I made ugly faces, it would freeze
 and I would stay like that."
 
 Johnny looked up and replied, "Well, Ms Smith, you can't say you
 weren't warned."
