Don't try this at home

Just been reading about a performance artist in Moscow who decided to make his point (ouch) by nailing his scrotum to Red Square. Yes, that's right, I said Red Square.
Call me old-fashioned but whatever happened to writing a stiffly-worded letter to one of your elected officials? I suppose this guy may not have much faith in democracy but he's not going to be doing anything stiffly for the foreseeable future.
I've heard of nailing your colours to the mast but this is more a case of someone nailing their 'mast' to the colour.
