I just hit it againt the counter until the peal breaks then it starts behaving like a bouncing ball. I keep playing with the ball until the shards are small enough and then pull the peal that now is more like a skin.

Then wash it with running water to get rid of the remaining shards. This step helps cooling down the egg which after boiling is too hot anyway, but you can probably skip and just pull the remaining shards manually it if you are one of those people who can stand and prefer things superhot.
