At the end of a Get Smart episode, Max had shot the bad guy. He rushed over to the wounded man and told him an ambulance was on the way. The man said, "Don't bother. I'm a goner. Just do me one favor before I go". Max asked what the favor was and the man said, "Tell me My Mother the Car is coming back on TV". Max looked confused and asked why. The man replied, "Then I won't mind going so much".
