1. Set Yourself Free
This particular PSA was absolutely unexpected. Our very own Jessica Blankenship was taken aback (read about it here). Was it grotesque? Yes. Disturbing? Absolutely. But did it get the message across? Eh, it was a bit (a lot) over-the-top, but I think it got its message across.
2. Dumb Ways To Die
A light-hearted approach to warning passengers, this extremely catchy tune has grabbed the internet by the hair and has amassed over 70 million views on YouTube (and millions more on other channels and video players).
3. Sexting PSA
The Babble wrote up a nice piece about it here.
Fear is a wonderful, wonderful tool.
