Wish this one was mine... my girlfriend was working in a daycare, where they had of course talked in circle time before about not talking to strangers. When you think about it, to a child, "strangers" come across to be a pretty evil bunch.
Later in the year, a police officer came in as a guest speaker. He was asking the kids why they thought he had different parts of his uniform. When he asked why he had a gun, one kid immediately blurted out, "To shoot strangers!"
