An elderly man approached an attractive young woman in a supermarket.
'Excuse me," he said, 'I can't seem to find my wife. Can you talk to me for a couple of minutes?'
The woman felt sorry for the old man and said, 'Of course. Do you know where your wife might be?'
'I have no idea, but every time I talk to a young woman like you, she seems to suddenly appear out of nowhere.'
