It's a good thing I'm not an airline pilot, because I don't think I'd be able to resist frakking with the passengers. Imagine being on hour 2 of a 7 hour flight, 36,000 ft in the air and the intercom comes on:

"Ladies and gentlemen, this is your Captain speaking. There is no cause for alarm."

Then it goes off.

Imagine what would be going through your mind.

Others (Mentally prefix each line with "Ladies and gentlemen, this is your Captain speaking")

"Oops." (no explanation)

"Is there a doctor/pilot/exorcist aboard? Please advise your stewardess."

"Please remain calm, the wings are...er...gone."
