The teacher in a public school had an incorrigible girl to deal with,
and for the twentieth time had taken her aside for a little
heart-to-heart talk on the subject of conduct, and was apparently making
a good impression on the child's mind, for she was attentive and
observant as she never had been before, not taking her eyes off the
teacher's face while she was talking, so that the teacher was inwardly
congratulating herself, until the scholar broke in with:
"Why, Miss Mary Jane, when you talk your upper jaw doesn't move a bit!"
