An Englishman, an irishman, a ravishing blonde and a homely brunette are sharing a compartment on a train as it winds its way through the Alps. Every now and then the train passes through a tunnel, during which time the compartment is plunged into complete darkness. On one such occasion, a ringing slap is heard and as the train passes back into daylight, the englishman is rubbing his sore red cheek. The brunette thinks I bet that dirty englishman fondled the blonde and she struck the pervert The blonde thinks I bet that filthy englishman was looking to grope me in the dark, mistook the dowdy brunette for me and she slapped the beast The englishman thinks I bet that stupid Irishman touched up the blonde in the dark and she slapped me by mistake The Irishman thinks I can not wait for another
