Ahhh... excuse me? Balking is allowed on a penalty kick? Seems like cheating to me.

Speaking of cheating, if my "buddy" ran up and appealed to the ref that I had purposefully stomped someone in the nuts when I was off balance (I watched it a half dozen times in slo-mo and at regular speed - no way that was on purpose) I might have done what Rooney did. And, I might have gone a bit further if I had known a wee shove would get me ejected.

I might be completely wrong... probably am.
