There's a Rastaman, a white man and a beautiful girl sitting next to each other on a train, with the girl being in the middle. The train goes through a tunnel and it gets completely dark.
Suddenly there is a kissing sound and then a loud slap!
As the train comes out of the tunnel, the woman looks perplexed while the Rastaman is sitting there looking angrily at the white man who is bent over holding his face which is red from an apparent slap.
Everybody else in the coach is laughing at him.
The white man is thinking to himself, "Damn it, that black guy must have tried to kiss the girl in the dark and she thought it was me and slapped me." The girl is thinking, "That man must have tried to take advantage of me in the dark, and kissed the Rastaman instead and got slapped. Serves him right."
Meanwhile, the Rastaman is thinking, "I-man hope dis train go though another tunnel soon so I-man can kiss the back of mi hand again and box dat blo*o*dclaat white bwoy one more time.
