A young Swedish woman, old Dutch woman, an Englishman, and an Irishman are riding a train.

A young Swedish woman, an old Dutch woman, an Englishman, and an Irishman are riding on a train.
The train goes through a tunnel, it becomes pitch black in the car, and then a loud SMACK is heard.
The train emerges from the tunnel and the Englishman is rubbing his cheek.
The old Dutch woman thinks: "He must have groped the young Swedish woman, and she slapped him."
The young Swedish woman thinks: "He must have tried to grope me, and accidentally got the old woman, and she slapped him."
The Englishman thinks: "The Irishman must have groped the Swedish girl, and she accidentally slapped me."
The Irishman thinks: "I can't wait for another tunnel so I can smack that English guy again."
