It worked on me. I rarely was spanked but when I was it was totally justified, and it did adjust my attitude.
I also remember well my PE coach. When a couple of kids where out of control, I was one. He would decide that each needed a licking. He would give the paddle to one to give give the licking to the other. The first thing that went through your mind was I do not like that SOB, the second thing that went through your mind is if I take it easy on him he may not take it easy on me. I wacked the Bast—d as hard as I could. He did the same to me.
My instructors logic worked! Both our asses hurt.
