Snopes take on the Hoax
I think this is a fascinating phenomenon. I've seen this particular hoax rise from a fark photoshop competition to become one of the most popular hoaxes this year.
The creator of this "hoax" didn't publish it to be a "hoax". It was simply part of a photoshopping competition, but I think it's risen so quickly because of an odd quirk of our Modern culture. It's the same reason we don't respect our elders anymore.
We think our elders are stupid.
