For me, the funny part about the campaign is its morbidity. The tagline of the ads is "Dumb ways to die" and apparently the campaign has been around for a few years. The ads feature jelly bean-looking "people" who are meeting creative demises, and each one ends with a train-related death in some way. There's even a series of YouTube videos.
Judging by the fact that there is also a website where you can purchase the jelly beans in the various forms of decease, I think the campaign was relatively popular.
I find the whole thing to be really funny, and you have to admit that the song is catchy. There are lots of parody videos on YouTube as well. Just search "Dumb Ways to Die" for an endless time suck.
These are the videos that I watch over and over as I wait for the train to come at Melbourne Central station after classes. Since class doesn't usually let out till 8:30 or 9:00, the train services have slowed to once ever 30 minutes or so and I'm often standing at the station for a while, so I've gotten to know the jelly beans pretty well.
I'm a little over it with the jelly beans, and if the campaign has been on since 2012 as YouTube would have me believe, I can only imagine everyone else in Melbourne is kind of over them, too.
There are also the official, not-filmed-while-standing-on-the-platform versions of the videos on YouTube. Just thought I'd show y'all what I see all the time in the interest of vicariousity.
