4. Dick Cheney
That the still-serving 46th Vice-President of the US is on this list has nothing to do with Iraq, Haliburton or dodgy deals of any sort.
Last year, Dick went hunting with a friend. And shot him.
Accidentally, of course. Cheney apparently confused 78-year-old Texas attorney Harry Whittington, with a quail. In the process Whittington was shot in the face, neck and upper torso with birdshot pellets. The National Review quoted Cheney's reaction as saying, 'Harry, I had no idea you were there!'
The owner of the ranch said, simply, that 'Mr Whittington got peppered pretty good.' Ouch.
