A policeman was taking a vandalism report at an elementary school when he was interrupted by a six year old girl. She looked up and down at his uniform and asked, "Are you a policeman?"
"Yes, I am," he said.
"My mother told me that if I ever needed help I should ask a policeman. Is that right," the girl asked.
"Yes it is," said the policeman.
The girl extended her foot to the policeman and said, "OK, then, would you tie my shoe?"
