A woman announces to her friend that she is getting married for the fourth
time.

"How wonderful! But I hope you don't mind me asking what happened to your
first husband?"

He ate poisonous mushrooms and died."

Oh, how tragic! What about your second husband?"

He ate poisonous mushrooms, too, and died."

Oh, how terrible! I'm almost afraid to ask you about your third husband."

He died of a broken neck."

A broken neck?"

He wouldn't eat the mushrooms."
