Joe the Plumber

Joe the Plumber's name isn't Joe. It's actually, Samuel. Turns out, that besides owing back taxes, Joe isn't a licensed plumber. Oops.

Oh, and he's related to Charles Keating of the Keating Five Scandal.

Other than the fact that he is operating under a sort of alias here, is a tax cheat, doesn't have professional licensure to do his job, and reminds everyone of the nadir of McCain's career, I am sure he's a real stand-up guy.
