After flying so many times, it's easy to find the "pre-flight instructions" to be a bit of a nuisance.  I usually just keep reading during them, so I would be inclined to find this a bit of a distraction!

I was on a flight once (NAS-CVG) with a flight attendant who was a bit on the ditzy side.  She somehow managed to get the seat-belt tangled up with the oxygen mask AND the cord on the microphone and nearly fell while trying to get them untangled.  She had this huge knotted-up mess hanging from the cord and eventually just gave up on untangling them and used the microphone then (and throughout the flight) with the stuff hanging from it.  About a half-hour into the flight, someone finally broke down and told her she forgot to take the life jacket off.  Now THAT was an entertaining way to give pre-flight instructions!  She was a trooper about it and found her own antics quite funny and never seemed flustered, so I don't feel too bad about laughing!
