Antiviral is an occasional column in which we run down the worst hoaxes, pranks, Photoshops and straight-out lies blowing up on the internet.

North Korean dear leader Kim Jong Un is a sonofabitch who offed his uncle last month. But he likely didn't strip naked Uncle Jang and slowly feed him alive to a pack of 120 starving dogs, as the media excitedly reported last week. In fact, that entire frenzy may have originated in a tweeter's dark-humored imagination.

Diamonds may be forever, but that doesn't mean they won't lie about their age. A new study reveals that gems that were once believed to be the world's oldest diamonds are actually fragments of polishing grit left behind by some other scientists.

A fake news article about a San Francisco elementary school suspending a child for saying "Merry Christmas" to an atheist teacher created a lot of real headaches for a similarly-named Bay Area school after the fake report went viral.

The New Jersey waitress who lied about receiving an anti-gay "tip" from a pair of local patrons has officially been let go from the restaurant where the controversial incident allegedly took place.

By now, you have probably heard of Linda Walther Tirado, aka "Killer Martinis," the Gawker commenter gone viral for her first-person "poverty thoughts." You may have also heard people say she's a privileged full-of-crap grifter. The truth is weirder and far more complex.

The warning signs were there, but the Internet (and Alec Baldwin) believed anyway.

Over the weekend, nearly everyone and their oversharing aunt got their fill of Bachelor producer Elan Gale's incredible tale of mile-high misogyny.

As though the saga of the internet's weirdest hoax wasn't weird enough already: A journalist nows claims she found out the art-pranksters behind YouTube series Pronunciation Book and the fake Twitter spambot Horse_ebooks—only to be lied to, manipulated, and "gaslit" for months by the two men and a circle of mutual friends.

As many suspected, the "Worst Twerk Fail EVER" video is a fake. Jimmy Kimmel, who had a hand in its making, confirmed it tonight on his show.

A.D. Harvey, the academic at the heart of this unbelievable (in the best way) Times Literary Supplement article from April, has finally broken his silence to The Guardian. (Read the Times Literary Supplement piece first; it's worth it.)

The Texas psychic responsible for giving local law enforcement officials a bogus tip on a mass grave at the home of a Liberty County couple will need to pay $7 million for the damage she caused the two.

In February, rap magazine The Source reported that 46-year-old Bronx rapper Tim Dog had died from "a seizure following a long bout with diabetes." But now a warrant for his arrest has been issued, following increasing evidence that Tim "Tim Dog" Blair faked his own death to escape thousands of dollars in debt.

The internet got excited yesterday when an old man living in a Vietnamese jungle identified himself as Sgt. John Hartley Robinson, a US soldier who disappeared in Laos in 1968. Interest spiked in an upcoming documentary about the man, who'd raised a Vietnamese family. There was only problem: He was a liar.

For about 20 minutes this morning, the top headline on the Drudge Report was "DRONES TO DELIVER NEWSPAPERS." It was a nice bit for Drudge, one that satisfied both his obsession with drones and his obsession with media, and had a good future-shock value for his aging, perpetually terrified audience. It was also, obviously, an April Fool's Day joke.

Today is April Fool's Day, a magical 24-hour spell during which companies spend lots of money to make stupid changes to their websites as a joke instead of as a business decision. In the spirit of public service we'd like to remind you: Don't trust anything you hear today. "Google Nose BETA," the search engine for scents? No. YouTube shutting down in preparation for finding the best video of all time? No. Twitter charging for vowels? No. Google Maps' new "treasure map" setting? Not real, and also not really even a joke. As usual, tech companies are the worst offenders in the publicity-in-exchange-for-saying-things-that-aren't-true game, but marketers have been gearing up for this for weeks, too. And TV: Good Morning America had a segment on a gorilla language this morning, and the Today Show had a Chris Brown "Breezy Flash Mob" complete with an interview. (Oh, no, wait: Today actually interviewed a violent and unrepentant abuser and hosted his insane fans outside its studio.) The prize for politics-related April Fool's is a tie between Sen. Ted Cruz who made a horrifically ugly April Fool's image macro for his Twitter, and the Yale Daily News, which straight-facedly announces that Hillary Clinton is joining the Jackson Institute for Global Affairs. (Ah: that famous New Haven sense of humor.) I don't have a clear memory of anything that happened before, say, 2005, so I have to ask: Was April Fool's Day always this excruciating? Or is this all—the endless stream of bad non-jokes, the news coverage of the bad non-jokes, and the grumpy bloggers whining about the above—the internet's fault? April Fool's! I already know the answer: Human beings have always been embarrassing and unfunny, well before the internet. [Lifehacker | NYT | USAT]

The recent Girl Scout cookie crime wave continued last week when two Oregon Girl Scout troops were hoaxed by a fake order for 6,000 boxes of cookies worth roughly $24,000. By the time the troops realized the order was not real, the troop had already paid for and set aside the 500 cases of cookies necessary to fill the fake purchase.

You may have heard by now that Urban Outfitters' favorite street artist, Banksy, was arrested in London last night on charges of vandalism. Even better, after hauling him in, police reportedly revealed Banksy's identity to the press, a huge development considering that for years everyone—including Gawker—has been doggedly speculating about who exactly is behind the world's most famous irreverent stencils and the critically lauded film Exit Through the Gift Shop. Isn't this exciting news? No, it is not, because it's all a lie.

I never want a boyfriend until I meet him; Charles* got me effortlessly. He enlivened me. I felt free to say whatever as we swapped pop-cultural obsessions, revealing ourselves in the process. Or at least, that was the idea. I told him I was nasty like the dirt under SWV singer Coko's fingernails. I meant it.

On Thursday evening, a Facebook user named Nolan Daniels posted a poorly-photoshopped picture of his supposedly-winning Powerball ticket, along with the offer that he would give $1 million to a random person who shared it. So far it's been shared over 200,000 times, because Like-addled Facebook users will share anything no matter how obviously untrue it is.
