Julia Gillard, the Australian prime minister whose parliamentary speech against misogyny made her a viral video star earlier in October, returns to YouTube with a faux national address in which she affirms the Mayan doomsday prophecy. Just to be clear, this video was created as a promotional clip for the Australian radio station Triple J.

A photograph of a man holding up what appears to be a winning Powerball ticket has gone viral on Facebook, except it's unmistakably fake (trivia: the first five numbers of Powerball tickets are always printed in numerical order). Uploaded by a Facebook user named Nolan Daniels, the picture is accompanied by a message that is already too good to be true: "Share this photo and I will give a random person 1 million dollars!" As of Friday evening, the post has accumulated more than 968,000 shares on Facebook and will likely break through 1 million shares in the matter of hours.

Taking the Venom concept one step further, this terrific optical illusion has some serious bite.

Robo-Fish: You'll have to change their batteries eventually -- can you handle that?

Potential Viral Ad of the Day: The overwhelming consensus is that this video of a "hacker" using a transmitter plugged into an iPhone to take over digital billboards is beyond fake and is most likely a viral ad for something.

I can't figure out what he might be selling, but if it's that transmitter, I'll take a dozen.
