"I just buried my second wife," the widower said to his secretary, "and i've vowed never to marry again."

"That's a shame," said the secretary, "but you know-it helps to talk about these things. What happened to your wives?"

"Well," he sighed, "The first one died after eating poisoned mushrooms, and the second one was shot to death."

"Shot!" the secretary gasped. "How horrible!"

"Yes," said the widower. "She wouldn't eat her mushrooms."
