A buzzer sits to the side of the podium. It has a green light so long as the speaker still has time to talk. When time is running out, it turns yellow. When time is up, it begins to flash red and buzz. Imagine an alarm clock set to its most annoying setting and you’ve got the sound. I just thought I would point this out because the buzzer reminds me of the hook from the olden days. You know, when the performer starts to bomb, a wooden hook comes from stage left and yanks the person off-stage. I think the buzzer is probably more humane. Everybody has the right to speak, I know. But for some of these people ... bring out the hook.
