It could be argued that the human body is not meant to possess the kind of raw physical strength that some of these bodybuilders bring to the table. If things go bad, they’re capable of causing a lot of damage with their bare hands. Take Ruben Arzu, a massive 300-pound mammoth of a man from Colton, California. How would you feel if you came home from a party and saw him stark naked on your lawn with menace in his eyes? That’s what happened to a Southern California couple in 2011. Arzu attacked the husband immediately, savagely beating him and breaking his jaw. When the wife ran inside to call the police, Arzu grabbed her by the head and fractured her skull. Thankfully, nobody was killed and the rampaging hulk was taken into custody.
