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. Then, 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 than what's the great news?!", Mr. Wilkens demanded.

The policeman said, "We're going to pull her up again tomorrow morning."
