Event listener, help!

If ten mc’s are going to have the same MOUSE_DOWN event, how can I, inside the mouseDown-function, know which mc it is? Like;


for(var i=0;i<10;i++) {
this["mc"+i].addEventListener(MouseEvent.MOUSE_DOWN, press);
}
function press(e:Event) {
 // lol? Could it be mc0 or mc2 or mc9? wtf...
}
