Mistakes happen, right? Well, hopefully not the kind of mistake shown in the video for "It's a Mistake" by Men at Work. But surely a lot of people around the world must have worried that with so much destructive firepower and a bunch of edgy leaders, even the littlest thing might set it all off. Remember that clip of Reagan making a joke about outlawing the Soviet Union? I'm glad the president had a sense of humor, but it would be nice if someone had told him when the microphone was on! Oh well, mistakes happen, right?
