Apparently, you need no qualifications or even an interesting story to be able to write your memoirs and have them published. Case in point, Steve O of Jackass fame has published his memoir entitled Steve-O Professional Idiot - A Memoir. He's got the "professional idiot" part down pat. I just have to shake my head and roll my eyes. He has come back from a dark history of drug addiction, so that part of the story may be interesting....it will just be interspersed with exploding toilets and flying midgets.
Still, reading this I would be afraid of losing brain cells so I think I'll pass.
