There was a Frenchman, an Englishman and Claudia Schiffer sitting together in a carriage in a train going through Provence.
Suddenly the train went through a tunnel and as it was an old style train, there were no lights in the carriages and it went completely dark. Then there was a kissing noise and the sound of a really loud slap. When the train came out of the tunnel, Claudia Schiffer and the Englishman were sitting as if nothing had happened and the Frenchman had his hand against his face as if he had been slapped there.
The Frenchman was thinking, "The English fella must have kissed Claudia Schiffer and she missed him and slapped me instead."
Claudia Schiffer was thinking, "The French fella must have tried to kiss me and actually kissed the Englishman and got slapped for it."
And the Englishman was thinking, "This is great. The next time the train goes through a tunnel I'll make another kissing noise and slap that French bastard again."
