Tru dat. Not sure the year it began, but when I was in grade school in the 60s and 70s, if you screwed off too bad, the teacher would kick your ass, then send you home and then the old man really let you have it. In 7th grade I think, one kid had big Elvis sideburns and the gym teacher didn't like them and told the kid to shave them off. Not sure why it was any of his business. When the kid didn't, one day in the gym lockers, he held the kid down with the help of a few others and they shaved one of them off, leaving the other. The kid went home with one big side burn.
Not only didn't the teacher get in trouble, apparently the parents agreed or felt that the school was in its rights to set standards, but when he came to school the next day, his other sideburn was now trimmed to match the other.
We all had a little chuckle then life went on and all was forgotten.
