Before the Operation

An elderly man was on the operating table nervous about the surgery about to be performed by his son, a famous surgeon.
Just before they put him under, he asked to speak to his son.
When his son came into the room, the patient asked everyone to leave, then motioned for his son to come closer.
Concerned, the famous surgeon said “Dad, are you worried about the surgery? You know there’s nothing to worry about, I’ve done hundreds of them and they were all successful.”
The father replied, “I know son. I know everything will go well, but just in case it doesn’t and something happens to me, keep in mind your mother is going to come and live with you and your family forever.”
