There's a white guy, a black guy and a beautiful woman sitting next to each other on a train. The train goes through a tunnel and everything gets dark. Suddenly there is a kissing sound and then a slap!! The train comes out of the tunnel. The woman and the white guy are sitting there looking perplexed. The black guy is bent over holding his face from an apparent slap. The black guy is thinking "Oh God, that white guy must have tried to kiss this lady, she thought it was me and slapped me." The lady is thinking, " That black guy must have moved to kiss me and kissed the man beside me instead and got slapped." The white is thinking to himself...."I hope the train goes through another tunnel, I could make another kissing sound and slap that black again."
