In a train carriage there was Bill Clinton, George Bush, Janet Reno and Bo Derek.
After several minutes of the trip, the train passes through a dark tunnel and the
unmistakable sound of a slap is heard.

When they leave the tunnel, Clinton has a big red slap mark on his cheek.

(1) Bo Derek thought - "That sleazeball Clinton wanted to touch me and by mistake,
he must have put his hand on Janet Reno, who in turn must have slapped his face."

(2) Janet Reno thought - "That dirty Bill Clinton laid his hands on Bo Derek and she
smacked him."

(3) Bill Clinton thought - "George put his hand on Bo Derek and by mistake she slapped
me."

(4) George Bush thought - "I hope there's another tunnel soon so I can smack Clinton
again."
