A Welshman, a Scot and a beautiful English girl are riding through the English countryside on a train in 1880. The train enters a tunnel and, since rail travel was still primitive then, their car is suddenly pitched into darkness. There is the sound of a kiss, followed by the sound of a slap. When they emerge from the tunnel, the Welshman has his hand on his cheek and has a shocked expression. He's thinking: I bet the Scot kissed the girl, and she tried to slap him but hit me instead. The girl is thining: I bet the Welshman tried to kiss me, but he kissed the Scottie instead and got slapped. The Scot is thinking: I hope we go through another tunnel so I can make another kissy sound and slap the Welsh bastard again.
