SYDNEY, June 24: An Australian public service ad campaign that became an internet hit for its black-humored list of reckless ways to die – such as “poke a stick at a grizzly bear” – has added to its luster by scooping up a record number of international advertising prizes. The three-minute short co-produced by government rail service Metro Trains to teach people to be careful around trains, ‘Dumb Ways to Die’, has notched up more than 50 million views on YouTube since its release in November 2012, sparked hundreds of parodies and even become a smartphone game.
