In a train car there was a Canadian, an American, 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 American had a big red slap mark on his cheek.

• (1) The blonde thought - "That American son of a bitch wanted 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 - "This dirty old American laid his hands on the blonde and she smacked him".

• (3) The American thought - "That dumb Canadian put his hand on that blonde and by mistake she slapped me".

• (4) The Canadian thought - "I hope there's another tunnel soon so I can smack that fuckin' American again".
