Guardian: "I've seen a photo of a young American soldier with two Iraqi boys. There is no nakedness or torture, but it is no less nasty for that. The boys are holding a cardboard sign. They and the soldier are smiling and doing a thumbs up. He is pointing at the cardboard sign, on which he's written: 'Lcpl Boudreaux killed my Dad. then he knocked up my sister!' Imagine the scene: Lance Corporal Boudreaux, a soldier on a liberating, civilising mission, asks the natives to pose for a 'memento'. He gives them the sign to hold. What lie did he tell them about its message? 'Iraq is liberated', or 'Mission accomplished'? And who, in this scene, is the more civilised?"

Here is the purported picture.

Of course this could just be a Photoshop creation. Snopes has no definitive answer.
