Slap Happy

In a train carriage there was Bill Clinton, George Bush, 
Janet Reno and a beautiful blonde. 
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. 

 The blonde 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."

Janet Reno thought - 
"That dirty Bill Clinton laid his hands 
on the blonde and she smacked him." 

Bill Clinton thought - 
"George put his hand on the blonde and 
by mistake she slapped me." 

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