I managed to find a blog entry of this Iraqi man living in Baghdad who was singing Cat Stevens' "Peace Train" and, just as he sang the line, "Now I've been happy lately," a stray bullet flies into his room. He says:
It's like no one should be happy in this country, because if you say that you're happy, a bullet will come and smash your head right away.
And the worst part is, all he can do is laugh about it.
BTW, here is the recording of the incident that he posted.
