Joke of the day. Are you ready?

While cruising at thirty thousand feet, the airplane shuddered. A passenger looked out the window. "Good lord!" he screamed. "One of the engines just blew up!" Other passengers left their seats and came running over; suddenly the aircraft was rocked by a second blast as yet another engine exploded on the other side. The passengers were in a panic now, and even the flight attendants couldn't maintain order. Just then, standing tall and smiling confidently, the pilot strode from the cockpit and assured everyone that there was nothing to worry about. His words and his demeanor seemed to make most of the passengers feel better, and they sat down as the pilot calmly walked to the door of the aircraft. There, he grabbed several packages from under the seats and began handing them to the flight attendants. Each crew member attached the package to his or her back. "Say," spoke up an alert passenger, "aren't those parachutes?" The pilot said they were. The passenger went on, "But I thought you said there was nothing to worry about?" "There isn't," replied the pilot as the third engine exploded. "We're going to get help."
