YouTube’s 20 Most-Shared Ads in November

1. Dumb Ways to Die (Melbourne Metro)

This hilarious dark humor campaign was launched by the Metro Trains Melbourne to reduce accidents on the rails network. The ad shows a series of characters dying in very weird and dumb ways. Like exposing their private parts to piranhas or setting themselves on fire. These dumb accidents are then likened to dying in preventable train accidents, like running across the platform.

The world of YouTube ads had a little bit of everything, from eye-popping extreme sports ads by Red Bull and DC Shoes to touching Christmas ads as well as three -- no kidding, three -- videos featuring Justin Bieber.

The most shared, though, was the imaginative infomercial created by Melbourne's public transportation authority to warn commuters of the dangers of crossing the rails or standing too close to the platform edge. Titled "Dumb Ways to Die," the ad features colorful fruit cartoons dying in the most unimaginable ways. The dark humor and funny delivery turns out to be a very effective way of saying "Just be careful."
