Two blondes were flying on an airplane when all of the sudden, they felt this huge jolt. They looked out the window and saw the farthest left engine on fire. The captain came over the loud speaker and said, "I don't want you to panic, but I know you felt that jolt, and I just want to let you know, that the farthest left engine has gone out. But don't worry, this plane is equipped to fly with three engines. We will make it to our destination, it will just take us an hour longer.
So the two blondes continued chatting. Twenty minutes later, they felt another big jolt. The captain came on again, "Please don't worry, we have lost another engine, but the plane can handle flying like this. It will just take us three hours to get to our stop."
The blondes looked at each other, a little worried. After another few minutes, bam, they felt another painful bump. Again, the captain came on, "I am sorry, but once again, one of the engines has gone out. We will however, be able to make it, but it will take five hours to get there."
The blondes were really worried now, and one of them said to the other, "You realize that if the other engine goes out, we're gonna be up here forever?"
