A older gentleman was on operating table

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 anesthesia he asked to speak to his son.

“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 is going to come and live with you and your wife.”
