Old Joke but funny!!

General Musharaf, Vajpayee, Madhuri Dixit and Margaret Thatcher are sitting in a train. The train goes through a dark tunnel. Suddenly there is a kissing sound and then a slap! The train comes out of the tunnel. The women and Vajpayee are sitting there looking perplexed. Musharaf is bent over holding his face, which is red from an apparent slap. All of them remain diplomatic and nobody says anything.
Thatcher is thinking: "These Pakistanis are all crazy after Madhuri. Musharaf must have tried to kiss her in the tunnel. Very proper that she slapped him."
Madhuri is thinking: "Musharaf must have moved to kiss me, and kissed Margaret instead and got slapped."
Musharaf is thinking: "Damn it, Vajpayee must have tried to kiss Madhuri, she thought it was me and slapped me."
Vajpayee is thinking: "If this train goes through another tunnel, I could make another kissing sound and slap Musharaf again."
