An American man, an Iraqi man, a beautiful girl and an old woman are sitting in a train. The train suddenly goes through a tunnel and it gets completely dark.
Suddenly there is a kissing sound and then a loud noise that sounds like a slap. The train comes out of the tunnel. The old woman, beautiful girl and the American guy are sitting there looking perplexed.
The Iraqi is bent over holding his face which is red from an apparent slap.

The old woman is thinking : "That Iraqi guy must have tried to kiss that girl and got slapped. "

The Iraqi is thinking : "Damn it,that American guy must have tried to kiss the girl, she thought it was me and slapped me instead."

The beautiful girl is thinking : "That Iraqi must have moved to kiss me,but kissed the old lady instead and got slapped."

The American is thinking: "If this train goes through another tunnel, I could make another kissing sound and slap that Iraqi again.
