Look at what all of these individuals have in common. They like to bite their lips. If you don't know these people the first man biting his lip is NY Governor Eliot Spitzer, then my governor Rod Blagojevich, and then of course you see the 42nd President of the United States Bill Clinton. If I recall correctly I've seen a number of pictures of Blagojevich biting his lip, especially last year when he couldn't seem to win a victory to save his life. Clinton well I'm sure he bit his lip thanks to Monica Lewinsky and other scandals that came up during his presidency.
What about Spitzer though? Well today he has a reason to get caught biting his lip today. Yup a recurring theme amongst mostly Democratic politicians although I can't say for sure whether or not a Republican has or hasn't been caught biting their lip.
ADDITION: Gov. Spitzer is expected to resign tonight he was only governor for more than a full year.
