My dad did that once. He hit a tiny tree that had just been planted and it somehow riccocheted back and hit him in the leg. Funniest thing I've ever seen. The tree was so small that there was no way that should have happened, but somehow it did. I wish I had thought to mention the 2 stroke penalty. That would have been even better.
And for anyone who watched the playoff, they saw that the rules officials were quickly offering up options to Watson on where he could drop his ball after he hit it into the water. He wasn't even asking and the guy was quick to mention that he could also go to the other side or back on the line of flight, into the fairway. So if they're only there to answer questions, he overstepped his bounds a bit.
They needed to clear the people out of the thing while he was hitting. With them standing there, no one had a clue how big the thing was and it definitely looked like a small patch of sand. They screwed up big time and you can be sure they'll change things up majorly in 2015 because of it.
