A couple of friends were flying to Rome for a holiday. An hour into the trip, the flight attendant came on the intercom and said, "The pilot has just informed me that we've lost an engine. There's no need for alarm, though. We have three engines left, and we'll just be an hour late."

About another hour into the flight she made another announcement. ''We've lost another engine. Don't worry. We still have two more, but we'll be another hour late.''

One guy turned to his friend and said, ''Man, if we lose the other two engines, we'll be up here all day.''
