Watch Maury or Rikki Lake and see how many of the kids who act up wear nice clothes and have a lot of confidence while the parent cowers and cries. If you have a problem child, a real problem child (I don't know if this kid fits the bill), then you can take away his self confidence by doing this, or making him wear embarrassing clothes. IMO, a last resort.
3 kids, no real problems that weren't immediately taken care of.
