Working on the fourth husband.

A woman tells her friend
she is getting married for
the fourth time.
"How wonderful! 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 also ate poisonous
mushrooms 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."
