McGrath, I'm very familiar with the term "shit-eating grin" - great big toothy smile, and none of it reaches the eyes. I'd always thought people used it to cover up guilt, but I don't know if many politicians are capable of feeling guilt. Certainly not Saddam. It might be a manifestation of fear, it might be a full-face smirk due to (as Harvey said) knowing something we don't or attempting to give us that impression. With Saddam, it may be that jolly mood I believe some dangerously insane people get in right before they make party favors out of your teeth and finger bones. (That may be the Jack Nicholson grin.)
