A man was reading the paper when an ad caught his eye: $500 Porsche!
New! The man thought that it was very unusual to sell a Porsche for
$500, and he thought it might be a joke, but thought it was worth a
shot. So he went to the lady s house and sure enough, she had an
almost brand new Porsche.
"Wow!" the man said. "Can I take it for a test drive?" Unlike what he
expected, the man found that the car ran perfectly and took it back to
the lady s house.
"Why are you selling me this great Porsche for only $500?"
"My husband just ran off with his secretary, and he told me I could
have the house and the furniture as long as I sold his Porsche and
sent him the money."
