Journey by Stephen Clark  
    to Ridgetown You told a lie for Bob

 
 
Bob's wife looks at you suspiciously. "So you're a friend of Bob's?", she asks.
    "Yes."
    "Well what does he do for a living?"
    Bob is signalling you from behind his wife -- he's doing the action of brushing his teeth.
 
Say, "He's a toothpaste salesman?"
Say, "He's a dentist?"
