When I was 14 I saw a teacher punish a boy by forcing him to take of his clothes in the school's yard. I never found out what he did wrong, but she did intentionally if front of both girls and boys to humiliated him. I remember I was sitting with my girl friends watching him with his penis exposed because she never let him cover it with his hands. I'll never forget the embarrassed look on his face as she paraded him across the yard crying into the school building, down a crowed hall way filled with students with out a stich of clothing on. I remember girls telling each other "did you see his dick" when she knew damn well we had all see plenty of him. Later that afternoon we saw him walking out of the principal's office and didn't even dare look at any of us in the eye. It was an elementary boarding school for girls and boys ages 6 to 14 and nudity at that age wasn't an issue. We had all seen teachers spanking boys with their pants and undies down but never completely naked. I'm sure the use of nudity in front of other male and female students was a very effective way to punish misbehavior. I don't know if they still do that in schools or has been long out lawed, but in boarding schools where no outsider know what goes on in there, I think they still do it.
