A policeman rings the bell of a home at 6 am one morning. When the man answers the policeman says "Sir, I have some news for you. In fact, I have some bad news, some good news and some great news." The man says "Well, let me have the bad news first." The policeman says "I'm sorry to inform you that we just pulled your wife's body out of San Francisco Bay." "My God! That's awful!" yells the man. After he composes himself he sobs "Well, what's the good news?" The policeman says "Attached to her body were two dozen cherrystone clams and a dozen dungeness crabs." "My God! That's absolutely terrible!" screams the man. Composing himself again he sobs to the policeman "Please tell me your great news." The policman smiles and says "We're pulling her up again at 6 am tomorrow morning."
