This week, news outlets around the world sentenced their readers to indefinite self-detention, subjecting them to the story of a man who found a spider living under his skin while traveling abroad. According to articles by The Telegraph, the Daily News and Buzzfeed, the venomous vagabond tunneled through Australian Dylan Thomas for three goddamn days, until doctors "finally found out it was a tropical spider" and surgically removed it.

Unsurprisingly, experts have disputed the tale seemingly stitched together from Snopes' greatest hits. Speaking to io9 and WAtoday, five different doctors and researchers called bullshit on Thomas' story, most noting that spiders aren't particularly built for burrowing or surviving without air. "[I]n general this is impossible and there is no reason that a spider would do that," said arachnologist Dr. Charles Griswold, reckoning even spiders have enough sense not to try something so dumb.

While Ebola itself remains incredibly rare in the U.S., Ebola hysteria became endemic in America this week after two healthcare workers tested positive for the disease.

Perhaps the glurge-iest expression of the collective freak-out was the breathless coverage of Bentley, the quarantined Cavalier King Charles Spaniel belonging to one of the infected nurses. The above photo, used in both the Daily Mail and New York Post versions of the Bentley story, was widely circulated online, putting a Precious Moments™-worthy face on the deadly virus.

But as the Daily Dot noted, that picture is of a different pup entirely, one named Penny. First posted 16 months ago (original hashtags: #ckcs #cavlife #cavalierkingcharles #blenheim #dogsofinstagram #instadog #dogoftheday #puppy #puppyeyes #cute #adorable #omg), Penny's owner seems to be taking the image's misattribution in stride, sharing a headline from Slate on Wednesday that read, "Dog in Quarantine Isn't Adorable Dog in Bath Photo, Remains Cute Nonetheless."

After months of dormancy, this long-debunked image of Stevie Wonder shilling for Atari popped up online again last Saturday. Unfortunately for smug present day-ers, the picture is just a doctored version of a much more sensible Stevie Wonder endorsement for the classic Mu-Tron III funk filter.

This incredibly clueless image, however, is absolutely real. Taken from 1942's How Boys and Girls Can Help Win the War, the illustration appears on page 43 of the propaganda rag. Luckily, the comic more than makes up for its racial insensitivity with helpful tips like "All the track stars take hurdles in stride because they make tracks to the table and eat butter and similar spread every single day!"

An embarrassing number of news sites published this image on Monday, including the Daily Mail, the Huffington Post and the Daily Express, which asked, "Is this Crabzilla?" Originating from the website Weird Whitsable (dedicated to "Phantoms, Mysteries, Tall Tales and Artifacts"), British papers estimated the creature to be "at least 50 ft. wide."

As a number of sources soon pointed out, the picture is in reality a Photoshopped satellite image, cleverly taken by the forger from the last place anyone would look, Bing Maps.

By Thursday, even Weird Whitsable proprietor Quinton Winter seemed to understand the jig was up, telling Kent Online, "I'm not trying to lie about anything, it's just a bit of fun."
