Remember the 1990's jabbering cars? "A door is ajar". "Turn your headlights on". So the guy who borrowed one of those told the guy who lent it to him "I got some good news, and some bad news." The man groans, and says "Gimme the bad news first". The reply was "I drove your car off a cliff." "WHAT!!??! What could possibly be good news in that?" "Well, I got 600 mpg while I was doing it!"
