Pretty Blonde

One day a blonde was riding on an airplane. There was a loud
noise that came from outside the plane. The captain came on
the intercom, "Attention passengers, we just lost one of our
engines; but don't worry, the other three engines will keep
us up. Also, we will arrive at our destination about an hour
behind schedule."

Half an hour later, another loud noise sounded from outside
the plane. The captain once again came on the intercom,
"Attention passengers, do not be alarmed. We lost another
engine, but the other two will still keep us flying. We will
arrive at our destination about three hours late."

After the captain said this, the blonde leaned over to the
passenger next to her and said, "If those other two engines
go out, we'll be up here forever."
