While I'm used to the Nigerian email scams that regularly offer me a share of wealth stashed by fleeing regimes, I have to say that this one really impressed me:

I know you would be surprised to read from someone relatively unknown to you before. My name is Sgt. Robert Greene, a member of the U.S. Marine Corps, which was deployed to Iraq in the beginning of the war in Iraq. I would like to share some highly personal classified information about my personal experience and role which I played in the pursuit of my career serving under the U.S 1st Marine Division which was at the fore-front of the war in Iraq.

Though, I would like to hold back certain information for security reasons for now until you have find the time to visit the BBC website stated below to enable you have insight as to what I’m intending to share with you, believing that it would be of your desired interest one way or the other.

The last sentence in the linked story is the kicker. You have to admit, when you have the BBC backing up your story, and a fairly recent story at that, it's a cut above in terms of sophistication.
