Advent Sunday Carol Service
There’s an improvisation game that actors play, called Headteacher, which goes like this. The teacher arrives late carrying the register and a pair of glasses. He starts to quieten down the class, but when he puts his glasses on he sees not a class but the school governors. He rapidly heads to the door, but the door sticks and he struggles to open it. Eventually he escapes, but re-enters the room a short while later, taking it to be the staff room.
