whisper whisper whisper whisper
You have been asked to form a line, in twos. The teacher informs you that it is necessary to be quiet, so you must whisper. Upon this decree, everyone must (audibly) whisper the words "whisper whisper whisper whisper" to one another. The teacher will acknowledge this with a grateful "all right, thank you".

A substitute teacher at my primary school would often say, \'All I want to hear is the hum of your working.\'
It backfired on us though, as there\'s only so long an entire class of kids can maintain the drone of a beehive before getting tired, losing interest, or looking disapprovingly at those who kept it up for longer than the collective joke was deemed amusing, leading to them being singled out for beatings later.
