An MC enters an auditorium. A huge roar erupts, which he quickly
waves down.
"I am not the main speaker", he says. "The main speaker has asked that all of
you who haven't "been there" should move out of earshot; and wear these
headphones - playing popular music - to ensure that you cannot be addressed".
The main speaker arrives and addresses the audience?
