Time magazine listed the Where The Hell Is Matt? video (which shows Matt Harding doing an odd little dance in various locations around the world) as the #1 viral video of 2008. But at a conference on December 11, Harding confessed that the video was just a hoax. He said the whole thing had been shot in front of a green screen, and that animatronic mannequins had been used to make it look like people were dancing with him. Check out the full video of his confession:
Now, when I watch this, I think it's obvious he's being sarcastic. He's making fun of people who are so paranoid they think everything is fake.
However, not everyone seems to recognize the sarcasm. I've run across some websites in the past few days that are reporting Harding's "confession" as a straight story, with no mention of sarcasm. For instance, check out this Associated Content article, which doesn't seem to be just playing along with the gag.
As the saying goes, "we are at our most gullible, when we are most skeptical."
