If they like Star Wars, show em the dark side...Diddy's Empire play set. The "wow" effect should fix their ass whew
spend more time with them.Practical explanations for discipline would be great in this thread, however your thoughts.
Another thought...
Remove the gaming console from his possession and let him use it only as a reward for his good behavior.
Once he starts showing some respect, limit his time on the console.
If he's gaming online, he's probably gaming with a bunch of adolescent adults that act just like him.
