You guys forgot the all important......take the packs out of high BEFORE you go to idle.

-DING-
me - Yes miss flight attendant?

FA - the lav smoke detector is beeping and there's a smoke cloud that smells like burnt dust.

me - don't worry, I'll fix that....(stupid packs!! $#%&**& piece of sh^&)

me - ladies and gentlemen, we've had one of our air conditioning packs overheat, don't be alarmed, the smoke in the cabin will dissipate shortly and there is nothing wrong with the aircraft......(just the dumb pilot)
