An older gentleman was on the operating table awaiting surgery and he insisted that his son, a renowned surgeon, perform the operation.

As he was about to get the anaesthesia, he asked to speak to his son.

Yes, Dad, what is it? the son asked.

Dont be nervous, son, the father smiled. Do your best and just remember, if it doesnt go well, if something happens to me, your mother is going to come and live with you and your wife
