BEFORE TAKE OFF:

"To operate your seat belt, insert the metal tab into the buckle, and pull tight. Actually, it works just like every other seat belt on the planet. If you don't know how to operate one, you probably shouldn't be out in public unsupervised."
and:
"In the event of a sudden loss of cabin pressure, oxygen masks will descend from the ceiling. Stop screaming, grab the mask, and pull it over your face. If you have a small child traveling with you, or someone who is acting like a small child, secure your mask before assisting with theirs. If you are traveling with two such persons, decide now which one you love more."

SHORTLY BEFORE ARRIVAL:

"Weather at our destination is 50 degrees, with some broken clouds; but they'll try to have them fixed before we arrive. Thank you, and remember, nobody loves you, or your travel money, more than this airline."

ON THE GROUND, AFTER AN EXCEEDINGLY BUMPY LANDING:

"Ladies and Gentlemen, please remain in your seats until Captain Crash' and the Crew have brought the aircraft to a screeching halt up against the gate. And, once the tire smoke has cleared and the warning bells are silenced, we'll open the door and you can pick your way through the wreckage to the terminal."

ON ARRIVAL:

"We'd like to thank you folks for flying with us today. And, the next time you get the insane urge to go blasting through the skies in a pressurized metal tube, we hope you'll think of us here at this airline."
