We've all see the labels that seem pretty obvious to us? "Pot may get hot when used on stove." "Slippery when wet." I could go on. But apparently, some people need to be reminded not to do dumb stuff. In Australia they've come up with a public service announcement for the Australian Metro to convince people to not ignore the signal at pedestrian crossings for their metro trains. And this PSA has a catchy tune called... "Dumb Ways to Die." The question is do we really need this kind of reminder? Unfortunately, for some people, yes.
