Deleting a MC from inside itself

Hey
I have a question which probably isent to difficult…
im making a game in which there are some mines which chase a ship…
these mines are created with


dot.duplicateMovieClip("dot"+currdot, this.getNextHighestDepth(), {_x:-100, _y:-20});
currdot=currdot+1

inside the dot MC there is a video , it blinks and roatates and stuff when its just floaring around , and when it hits something


if(this.hitTest(_root.ufo)){
_root.shieldCurr=_root.shieldCurr-_root.dotDamadge;
trace("hit"+this);
this.gotoAndPlay(73); 
}

gotoAndPlay(73); refers to the 1st frame of the explode animation inside the MC frame 1 to 72 is a looping animation
now after it plays the exploding animation , i want it to be deleted
ive tried a few different things like…


_parent.removeMovieClip(this);

which dont seem to be working.
So id like to remove the movie clip from inside itself , thank you.
