Reset the Trap

Goldstein and his wife are on a Caribbean cruise, when a huge wave sweeps Mrs. Goldstein overboard. A search doesn't find her body.

Goldstein, heartbroken, returns to New York.

A few weeks later, he gets a cable " We have located your wife's body. Also found a huge pearl, three inches in diameter, formed in her vagina. Please instruct."

Goldstein cables back: "Send me the pearl, and reset the trap."
