A Chinese, a Japanese, a slender dark haired girl, and a homely brunette... ...are sharing a compartment on a train as it winds its way through the mountains. 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 Japanese is rubbing his sore, red cheek. The dark haired girl thinks 'I bet that dirty Japanese fondled the blonde and she struck the pervert.' The brunette thinks 'I bet that filthy Japanese was looking to grope me in the dark, mistook the dowdy brunette for me and she slapped the beast.' The Japanese thinks 'I bet that perfidious Chinese touched up the blonde in the dark and she slapped me by mistake.' The Chinese thinks 'I can't wait for another tunnel so I can slap that Jap twat again.'
