Two statisticians were flying from LA to New York. About an hour into the flight, the pilot announced, "Unfortunately, we have lost an engine, but don't worry, there are three engines left. However, instead of five hours, it will take seven hours to get to New York."
A little later, he told the passengers that a second engine had failed. "But we still have two engines left; we're still fine, except now it will take ten hours to get to New York."
Somewhat later, the pilot again came on the intercom and announced that a third engine had died. "But never fear, because this plane can fly on a single engine. Of course, it will now take 18 hours to get to New York."
At this point, one statistician turned to the other and said, "Gee, I hope we don't lose that last engine, or we'll be up here forever..."
