An older gentleman was on the operating table awaiting surgery and he insisted that his son-in-law, a renowned surgeon, perform the operation.
As he was about to get the anesthesia, he asked to speak to his son-in-law. 'Yes, Dad, what is it?'
'Don't be nervous son; do your best and just remember, if it doesn't go well...... if something happens to me, your mother in law is going to come and live with you.'
The surgery was a great success.
