Never sit in an unlit train carriage

In a train carriage there was an Englishman, a Frenchman, a spectacular looking blonde and a frightfully awful looking fat lady.

After several minutes of the trip the train happens to pass through a dark tunnel, and the unmistakable sound of a slap is heard. When they leave the tunnel, the Frenchman had a big red slap mark on his cheek.

(1) The blonde thought - "That randy looking French guy must have tried to touch me and by mistake, he must have put his hand on the fat lady, who in turn must have slapped his face"

(2) The fat lady thought - "That dirty old Frenchman must have laid his hands on the blonde and she smacked him."

(3) The Frenchman thought - "That stupid Englishman must have put his hand on that blonde and by mistake she has slapped me."

(4) The Englishman thought -"I hope there's another tunnel soon so I can smack that French Sod again."
