There were two blondes on a flight to California. They are about two hours into the flight when the pilot announces that the plane had just lost an engine but everything will be fine since the plane have three more. However the flight will take an hour longer.
A half hour later the pilot announces that the plane has just lost another engine so the flight will take another half hour longer, with only two engines running.
One of the blondes says, "If we lose the two last engines we will be up here all day."
