Old Jewish Man

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

As he was about to receive the anesthesia he asked to speak to his son.

"Yes Dad, what is it?"

"Don't be nervous, 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."
