Video: Adam Parore is out hit-wicket after helmet falls on stumps

You would have seen Kevin Pietersen getting out like this in a Test against West Indies. Here is another time when the same incident occurred. 

In a match between Australia and New Zealand, Adam Parore is out hit-wicket and watching his helmet hit the stumps after missing a bouncer from Brett Lee. The umpires seem to have made the wrong call as in those days, any ball above the shoulder was considered a no ball.
