I was watching my brother play Bad company 2. He took alot of time climbing a mountain to snipe just to see that there were too many trees to actually shoot anything. In a fit of rage, he sprayed with his sniper rifle into the treeline. As he does, the game tells him that he just scored a headshot and got a kill. It took a good few minutes before I could take a breath and let my face stop being red from laughing.
