Art is subjective. What one person calls a masterpiece another might call nonsense. Where one person sees genius, another sees only madness.
Russian performance artist Pyotr Pavlensky took a swing at making an artistic/political statement when he nailed his scrotum to the cobblestone roads of Red Square. Police eventually detained Pavlensky, and covered him with a blanket.
Pavelensky's stunt was intended to protest the Russian police state, due to its concurrence with Russia's national Police Day. Though Pavelensky was detained, he was given medical attention and later released.
Given how the whole episode played out, Pavelensky's political statement was at best a mixed message. As an artistic statement, however, his actions were undoubtedly shocking and extreme. This isn't the first time Pavelensky has stretched the definition of what could be considered art -- and he is by no means the only one to do it.
