I hear what you are saying gorgo. Every good find on youtube.com turns out to be a hoax. I fall for every new viral almost every time on the first few views - then I find out the truth and feel cheated.
Now when someone posts something that looks out of this world, too crazy and has never been done before - it's a hoax.
This particular viral has had an excellent run here - I've counted five different people who've posted it.
