All my dad had to do was get out his belt and hang it on over the door knob. We knew it was time to behave!
My brother-in-law was a kid that was spanked regularly. He was one of the boys that just never cried. Even with broken bones and bike crashes and skinned up knees and elbows. My wife was the older sister and almost never got in trouble. She said one day she saw her brother getting yet another spanking and he was crying a little. My wife was amazed and after the spanking she asked him about it and in front of their mom he admitted he only cried because he figured his mom's arm was getting tired and he figured she would quit if he cried.
After that point the only punishment was no desert or extra chores, spanking was pointless.
Of course I was a model child. The kid that the other parents pointed to and asked their kids why they can't be good like me. My parents both are spinning in their graves I suspect.
