In a train car there was a Canadian, an American, a
spectacular looking blonde, and a frightfully awful
looking fat lady. After a while, 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.
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."
The fat lady thought - "That dirty old American laid
his hands on the blonde and she smacked him."
The American thought - "That damn Canadian put his
hand on that blonde and by mistake she slapped me."
The Canadian thought - "I hope there's another tunnel
soon--so I can smack that stupid American again."
