Actually, I'm getting flashbacks to my either my first or second year of teaching.
One of our 3rd Yr boys had bet the rest of the year group that he'd wear a skirt to school. (He'd borrowed a gym skirt from one of the girls.) I believe he made a great deal of money out of the caper. (And yes, I'm aware of the more recent case where a load of boys wore skirts as a protest against not being allowed shorts. This was strictly for monetary gain.)
I've no doubt that all concerned would be in huge trouble now, but this was a Fife high school at the time of the miners' strike.
The depute dealt with it by leaving the boy to sit outside the heidie's office all morning. (The heidie was out at a meeting.)
The boy's Guidance Teacher was a mature entrant to teaching. (This was a 'tough school' which made a point of hiring mature male teachers when possible.)
Some of the staff were former mineworkers. The GT had formerly been employed at Rosyth Dockyard.
As I walked past the hapless seated boy, I heard the GT remarking to another mature entrant "Well, what d'ye think of this, Mr X? We're going tae have tae get the Educational Psychologist tae this lad. He doesn't know whether he pees standing up or sitting down!"
ETA The GT is no longer in the land of the living and I'm now retired.
