Let the talking heads and bloggerati theorize about who John McCain and Barack Obama will choose as running mates, Mental Floss has taken another route.

Browse through and meet such illustrious American politicians as Richard M. Johnson, who "dressed like a farmhand (and) cursed like a sailor"; Andrew Johnson, who "took his 1865 vice presidential oath drunk as a skunk and belligerent as hell"; and Aaron Burr, who dispatched Alexander Hamilton with a bullet to the brain. It's enough to make you think we're downright civilized today.
