Sometimes I think this would be a good idea, at least for me. I think it would be easier to get cained or whipped for screwing up all the time, rather than having to remember to never make the mistake again. If it left a bruise, cut or scar or simply just hurt for a few hours...I think I'd be less likely to make the same mistake again, and I'd probably be on pretty good behavior for a while.
It's just a random idea that pops into my head a lot. I mean they pay me all this money to do my job right....not screw up all the time. I think it would be pretty effective in helping me get my act together.
Maybe I've really lost it, but then again....when I was a little kid it worked pretty well.
