ActionScript 2.0 :: How To Remove Element From (Special) Array

I am trying to remove elements form an array. The array is kind of special: content depends on what you have clicked or not:

Code:
pArr = [];
for(var i =0;i<max;i++){
johndoe[i].pressed = false;
johndoe[i].onPress = function(){
this.pressed = !this.pressed;
if(this.pressed){
pArr.push(this.obj)
}else{
pArr.remove(this.obj);
}}}

Of course the remove function is my pb, not done yet. How can I remove the same object from the array, knowing that the array can contain several times the same object, so I do not want to delete it many times but just the good one? So the trick is to remove only the object associated with the johndoe button. Maybe the pb comes from the way I push the elements?
