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