The day after a man lost his wife in a scuba diving  accident, he
 was greeted by two grim-faced policemen at his door.
 
 "We're sorry to call on you at this hour, Mr. Wilkens, but we have
 some information about your wife."
 
 "Well, tell me!" the man said.
 
 The policeman said, "We have some bad news, some good news, and
 some really great news. Which do you want to hear first?"
 
 Fearing the worse, Mr. Wilkens said, "Give me the bad news first."
 
 So the policeman said, "I'm sorry to tell you, sir, but this
 morning we found your wife's body in San Francisco Bay."
 
 "Oh my god!" said Mr. Wilkens, overcome by emotion. Remembering
 what the policeman had said, he asked, "What's the good news?"
 
 "Well," said the policeman, "when we pulled her up she had two
 five-pound lobsters and a dozen good size Dungeoness crabs on
 her."
 
 "If that's the good news, then what's the great news?" Mr. Wilkens
 demanded.
 
 The policeman said, "We're going to pull her up again tomorrow
 morning."
