It can be very entertaining when the crew on a legacy carrier let their hair down a bit and stray from "the book". Most of the time they seem terrified of getting in trouble with the FAA or their bosses at HQ.

To this day I laugh out loud at the comments made throughout a flight I took DEN-IND a few years back. The captain and purser were virtually a comedy team (the purser, in fact, WAS appearing at a Denver comedy club and wrote her own humor in the delivery style of Rita Rudner).

Examples:

"In the extremely unlikely event of a water landing on today's flight from Denver to Indianapolis, there are several important things you should know, the first of which is that we're at least 200 miles off course."

"Your seat cushion doubles as a flotation device. As our seats are extremely valuable to us, if you have to use it to stay afloat it will become your responsibility to save it, have it dry cleaned, and express mail it back to the airline at (address). If you fail to return it within 30 days, you will be barred from future flights."

"In the event of sudden cabin depressurization, oxygen masks will drop from the compartments above you. Carefully put on your mask and continue to wear it until instructed otherwise by a uniformed crew member or until someone in the Indianapolis terminal asks you why you have a margarine tub on your face."

We got deadpan zingers from either the purser or the captain every 20 minutes or so throughout the flight. Very funny.
