I was at a private school that had rules about the length of boys hair. One guy in particular always ignored the rule and the administration would tell him to get a hair cut every so often, but he never did. Eventually when his hair got about down to his shoulders the principal pulled him aside and told him his hair was twice the allowed length and by next week it needed to be shortened by half.
Monday rolls around and he comes in with half his head shaved, and the other side as long as ever. We were impressed by literal interpretation of the principal’s request, but it still ended up with him getting a suspension for a week and he had to shave the other side before he could come back.
