Sorry to dissapoint but think little children or any children will copy the violence on television I know some of you say but hey we will not copy but bullies disagree bullies started right about when cartoon violence was made. Bullies get ideas from television and they will literally hurt you so I think cartoon violence is for when you get older but that's not bad because you could be out on a day playing and getting exercise please lets have a DISCUSSION ABOUT THIS AND SHARE WHAT YOU SAY ABOUT THIS! I'm sensible so my mam and dad let me watch cartoon violence like the Simpson's itchy and scratchy show and besides if your mam and dad find out you will get cartoon violence of you and eek EVEN MORE. WARNING Do not atemp cartoon violence to little children who understand television.
