After years of drought, record rainfalls hit Texas and Oklahoma this month, resulting in deadly flash floods that have claimed the lives of 23 Americans so far. And, like any major news event in 2015, a side-product has been a surge of bullshit photos.

Some, like this widely-shared image of Houston’s submerged highways, are real but misattributed, showing the damage caused by Tropical Storm Allison in 2001. Others, like the improbable shark picture seen above, are just dumb photo manipulations.

As Snopes explained on Wednesday, this image has been in circulation for years, previously said to have been taken in Puerto Rico after 2011’s Hurricane Irene. In reality, the picture is a simple cut-and-paste job, lifting the fearsome fish from a decade-old photograph by Thomas P. Peshack.

Of course, actual photos of this week’s flooding are plenty cinematic on their own. As one Reddit user noted in his caption for this picture by David J. Phillip for the Associated Press, the destruction in Texas looks like a scene from post-apocalyptic fiction. Other images, like the below photo of Houstonians navigating the city by kayak, are positively surreal.

But this week wasn’t all death and devastation. On Friday, Ireland voted to legalize same-sex marriage, the first country in the world to do so. And it was seemingly done with divine approval, a rainbow appearing above the nation’s capital on the day of the vote.

However, as many noted over the weekend, rainbows aren’t just a symbol of gay pride in Ireland, but a cornerstone of the country’s leprechaun-based economy.

For whatever reason, fake photos of Marilyn Monroe (who, it should be noted, was fairly well-photographed in real life) abound on the internet, rivaled in number only by fake Marilyn Monroe quotes.

Many of these images, like the photograph by Andre de Dienes seen above that rocketed to the top of Reddit’s /r/Pics page on Sunday, show entirely different women who just happened to be blonde in the ‘60s.

As Monroe historian Marijane Gray writes in her mass-debunking of bogus Marilyn pictures, de Dienes was never able to photograph the starlet nude. From Buzzfeed:

He writes about her refusal to do nudes in his published journal. Chuck Murphy, the sole owner and copyright holder of the de Dienes estate, has stated definitively that Marilyn never posed nude for Andre and that the woman in this photo is an unknown model that is absolutely not Marilyn.

Finally, this month’s dumbest fake photo comes from popular Twitter shitpic mill @OMGFunniest_, which shared an altered version of this image by Albanian photographer Bess Hamiti.

As internet ombudsman @PicPedant pointed out on Wednesday, this particular photo is notable for being physically impossible, showing a moon supposedly reflecting the light of the star that’s also backlighting it.
