4 people sat in a carriage in a train. An Englishman, a pretty young blonde girl, an ugly old woman, and a German.
It all goes dark as the train goes thru a tunnel. In the dark there's the sound of an almighty slap, and when the train emerges from the tunnel the German is rubbing his face, and there's a huge red mark on his face.
The old lady thinks "I bet the German fondled the blonde and got slapped"
The blonde thinks "I bet the German tried to fondle me in the dark, got the old lady by mistake, and got slapped"
The German thinks "I bet that Englishman fondled the blonde in the dark, but the blonde thought it was me, and hit me"
The Englishman thinks "I hope there's another tunnel soon so i can slap that German tw@t again"
