removeChild (mc)

Ok so I made this “snow” script


stage.addEventListener(Event.ENTER_FRAME, blop);

function blop(e:Event):void {

var newCircle:BlueCircle = new BlueCircle();
this.addChild(newCircle);

newCircle.scaleX = Math.random();
newCircle.scaleY = newCircle.scaleX;

newCircle.x = Math.random()*550;
newCircle.y = 420;

newCircle.addEventListener(Event.ENTER_FRAME, goUp);
}

function goUp(e:Event):void {

var circleMC:MovieClip = MovieClip(e.target);

circleMC.y -= 3;

if (circleMC.y < 0) {
circleMC.removeEventListener(Event.ENTER_FRAME, goUp);
}
}

Now in the end where I got the “circleMC.removeEventListener(Event.ENTER_FRAME, goUp);” I’d like to also completely remove the MC from the stage.
Help please
