A man gets married and shortly afterwards his wife dies. A friend tries to console him and asks, "What happened to your wife?"
"She died of poison from eating mushrooms," said the husband.
This man gets married a second time, and not long after the marriage, this second wife dies. The same friend tries to console the grieving husband and asks, "What happened to your second wife?"
"She died of poison from eating mushrooms," was also the reply from the husband.
This man takes a third wife and, not very long after the marriage, the third wife dies.
The consoling friend asks, "What happened to your third wife? Was it mushroom poisoning?"
The grieving husband responds, "No, she died of a broken neck."
"A broken neck!" replies the friend.
"Yes," says the husband, "she wouldn't eat her mushrooms."
