A Pakistani, an Indian, a beautiful girl and an old woman are sitting in a train. The train suddenly goes thru a tunnel and... it gets completely dark. Suddenly there is a kissing sound and then a slap! The train comes out of the tunnel. The woman and the Indian are sitting there looking perplexed. The Pakistani is bent over holding his face which is red from an apparent slap. The old woman is thinking : "That pakistani must have tried to kiss that girl and has got slapped." The Pakistani is thinking : "Damn it, that Indian must have tried to kiss the girl, she thought it was me and slapped me." The girl is thinking : "That Pakistani must have moved to kiss me, and kissed the Indian instead and got slapped." The Indian is thinking : "If this train goes through another tunnel, I could make another kissing sound and slap that Pakistani again."
