Just looking at the first video makes me want to stay clear of it. If by chance you fell in, the action of the incoming waves would batter you to bits.
When I was there my family (Dad and cousin) got dangerously close just so that they could get "better" pictures... people do some stupid things sometimes...
I heard about this one guy show tried to get free soda out of the soda machine by shaking it and it fell over and pinned him to the ground. It took like 30 hours of pure torture before he died. He was found with his face covered in dry tear sweat, he was also found holding a picture of his family with his one free hand that was not pinned under the weight of the soda machine. It was really hilarious. Maybe he can be part of this Darwin Award thingy.
I know a story of a guy who was falsely accused of murder and sent to prison for life. He started breaking down mentally over the years watching his friends move on by marrying people they loved and having careers. While the guy rotting in prison started receiving no visitors after a few years in the joint. Not to mention all the hate he received from the other inmates and guards. While his friends were making memorable moments with their spouses he was crying alone in his cell at night.
Can this guy receive a Darwin Award? It's not like he is going to pass on his genes to anyone...
