I once hosted an event where each speaker was given a newfangled sound-amplifying gadget called a “microphone.” One speaker soon showed himself to be more than a little rambunctious. So I thought, well, what if I turn off his newfangled sound-amplifying gadget? So I had it turned off. That cured him, mid-rant.
Later in the same event, someone else poured a jug of water on one of the other speakers – but that’s another story.
