The pilot comes on the intercom and says there's no need to panic, etc., but it will take extra hour to get to the nearest airport.
Another engine goes out, and the pilot repeats his spiel, except that it's going to take two hours to land.
So the third engine dies, and the pilot...it will take four hours...
The first guy turns to the second, and says "I hope that last engine doesn't quit, or else we'll never get down."
LOL - good one Calvin.
