Overboard

An elderly couple was on a cruise and it was really stormy. They werestanding on the back of the boat watching the moon, when a wave cameup and washed the old woman overboard. They searched for days andcouldn't find her, so the captain sent the old man back to shore withthe promise that he would notify him as soon as they found something.
Three weeks went by and finally the old man got a fax from the boat.It read: "Sir, sorry to inform you, we found your wife dead at thebottom of the ocean in a crab trap. We hauled her up to the deck, andattached to her butt was an oyster and in it was a pearl worth$50,000. Please advise."
The old man faxed back: "Send me the pearl, and re-bait the trap."
