Right off the bat, the was the first thing I was thinking when I saw the pics. "That chain is long, if it ever breaks, its going to be violent to whatever is around it."
Edit:
After posting in this thread, I realized that when you get older, you no longer thing about how cool something is. When I was 15 and saw something like this I would be all like "F yeah man! That's awesome!!" Now that I'm older the only thing I can think of is "how can this take my testicles out now?"
