An Englishman, a Frenchmen, a young woman, and an old lady, are sitting together on a train when it goes through a tunnel. A loud slap is heard, and then the Frenchman is rubbing his face.
The old lady thinks ‘I bet he tried to touch the young woman, and she slapped him’
The young woman thinks ‘I bet he tried to touch the old lady thinking it was me, and she slapped him’
The Frenchman thinks ‘I bet the Englishman tried to touch the young woman, and she thought it was me, so she slapped me’
The Englishman thinks ‘I can’t wait for the next tunnel so I can slap him again’
