Occasionally, against all odds, you'll see an interesting or even enjoyable picture on the Internet. But is it worth sharing, or just another Photoshop job that belongs in the digital trash heap? Check in here and find out if that viral photo deserves an enthusiastic "forward" or a pitiless "delete."

When photos of this 18-inch "nightmare shrimp" caught in Florida began circulating online late last week, some doubted their authenticity, speculating the creature's apparent size was just the result of clever camera angles. Unfortunately for your chances of ever sleeping again, the Australian Museum's Dr. Shane Ahyong confirms this Lovecraftian terror is absolutely real.

"The animal certainly is a mantis shrimp," the decapod expert told Gawker, specifically identifying it as "Lysiosquilla scabricauda, a common species in the tropical western Atlantic, including Florida." According to Ahyong, 18 inches could be a realistic estimate of the dream-stealing arthropod, if measured from "the tip of the tail to the end of the outstretched claws." Dr. Darryl L. Felder of the University of Louisiana-Lafayette came to a similar conclusion, but noted that length would make it—in technical terms—"a really big one."

Fueled by the Internet's mysterious need to constantly praise, ridicule, crave and criticize pumpkin-fucking-spice, pictures of a pumpkin-flavored condom raced through Twitter last weekend, leading many to believe that their dreams of autumnally-infused oral had finally come true. On Monday, BuzzFeed reached out to Durex to verify the photo, receiving a denial that was completely groan-inducing (in a bad way).

"Durex has heard that people are saying we launched a 'Pumpkin Spice' condom," the jimmy hat giant told BuzzFeed. "We can't claim this one, but we do love it when people spice it up in the bedroom." Ugh.

As The Vane's Dennis Mersereau explained in detail earlier this week, the above graphic of a "record-shattering snowfall" supposedly coming this winter is complete malarkey:

[T]here is no scientific skill in predicting record-breaking snowfall across any region — let alone the entire country — this far in advance. Heck, we often have trouble pinning-down snowfall accumulations while the storm is happening.

In reality, the picture comes from a bogus article by faux-satirists and Antiviral regulars Empire News. As this week's most boringly plausible fake news story, it was also one of the most widely spread, and by Friday the article had been shared over a million times.

Good news, burger-loving goths: this clove-smoking cheeseburger is absolutely real. Bad news, burger-loving goths: unless, you live in the Far East, you won't be seeing one any time soon. Dyed with the squid ink and bamboo charcoal, the "KURO Pearl" is exclusively available at Japanese Burger King locations through early November.

Burger King Japan previously released a similarly black, shamefully cheese-less iteration of the KURO burger back in 2012 to celebrate their fifth anniversary in the country. According to Japanese website Gigazine, that sandwich's "black appearance makes a big impact, but the taste was surprisingly traditional."

JESUS CHRIST, PEOPLE, IT'S A JOKE

A pretty obvious parody of corporate America's glurgy, hand-on-heart 9/11 messages, right? Apparently not to some people, who believed a master hacker had taken over Arby's Twitter account in order to write "Arby's hates America. This is a real tweet."

A few irony-immune Internet users went even further, giving the clearly fake thing the full Rust Cohle treatment.

Like the Neil deGrasse Tyson subway photo uproar earlier this year, the entire situation was—as @boring_as_heck noted in his initial tweet—completely unreal.
