We had a gym/sports teacher who was a prop forward for Gloucester. As it was a private school he lived on the premises.
His cottage was right next to the gym. He was a right lazy ... person. Often he didn't even turn up for lessons.
One day we were in the gym, a small group didn't even get changed they were playing cards in the changing room. He actually turned up and flew into a rage. He got them all into the gym and lined them up near the climbing ropes. He also shouted at me to join them as I had been playing basketball and had thrown the ball into the storage area rather than walk it over.
We all got 6 enormous belts across our backsides with a climbing rope.
He once also confiscated my guitar that another kid had pinched and was playing and disturbing his class. Nothing to do with me. Kept it for a month. So punished me and not the miscreant.
When I was teaching, our games teacher and I chatted about this bloke cos he knew him, he was by then some kind of big wig in kids rugby and he said "He's coming over here next week do you want to see him?" At first I said "OK" then I got hold of him again and told him not to bother as I wouldn't be able to stop myself telling him what I though of him.
Funnily he was the only teacher I had that I really couldn't stand.
