Back in the days when flying wasn’t so much of a hassle (pre-9/11), I flew Southwest a lot. Somewhere I have a file of there best announcements. One I particularly recall when talking about the oxygen masks was:
“After you have put on your mask, please assist and children or anyone acting like children with their mask”
“After you have put on your mask, please assist and children or anyone acting like children with their mask”
Lol!
