Who Kiss Who And Who Slap Who ???

There's an Indian, Pakistani and a beautiful girl sitting next to each other, girl in the middle, in a train. The train goes through 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 Pakistani are sitting there looking perplexed. The Indian is bent over holding his face which is red from an apparent slap.

The Indian is thinking "Damn it, that Pakistani must have tried to kiss the girl, she thought it was me and slapped me."

The girl is thinking, "That Indian must have moved to kiss me, and kissed the Pakistani instead and got slapped."

What isPakistani thinking?

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