I don't recall a Family Guy episode, there was however a Robot Chicken Christmas Special where Santa tells a child his mother did not die well. There was also a similar quote from American Dad, Stan Smith tells a soldier he will live but not live well. You may be confused since Seth MacFarlane voiced Santa in the Robot Chicken Christmas Specials & voices Stan Smith.
