[Ol' Dan Tucker]

I bet if you were assigned to a work project where you were locked into a small room with little to do except talk to your lone coworker locked in with you for hours on end, and tape-recorded constantly, you might deliver something less than Ciceran oratory at some point too.

Get off your high horse.

No one locked them into a room. They were flying because that was their chosen profession. If they didn't like the conditions they could've walked away at any time.

Get off your high horse.

Read for comprehension.

Now that the insults are out of the way, my point was that even people who are highly trained professionals can joke around on the job without compromising their work. If a surgeon puts on some rock music or tells a nurse a joke, and his patient later dies because the life support machine fails, is the surgeon an "idiot" or unprofessional?
