Ranging from puppies being bewildered by a hall of mirrors to people sporting sci-fi-looking backpacks on a daily subway commute, r/hmmm is a treasure trove of hilariously absurd imagery. One that champions the hard-to-grasp ridiculousness that is internet humor, over logic and reason. As Haruki Murakami, the bestselling Japanese author famous for his often ambiguous writing style, once said: “Some things in life are simply too complicated to explain in any language.” To which we add: some things, just like the photos you see on this list, don’t need an explanation.

This might explain why almost 2 million internet users are fascinated by this content that could easily be labeled as ‘reality glitching out.’ Remember that scene from the original Matrix where Keanu Reeves sees a black cat walk by, followed by another one that behaves exactly the same way? Well, the following images might not bring a sense of déjà vu. But they will definitely serve as a reminder that our daily lives can be full of ludicrous surprises.

It’s hard to put a finger on what exactly makes these images so special, bringing us back for more every week or so. Is it the (David) Lynchian absurdity? Or perhaps the element of surprise? According to the subreddit’s guidelines, “as long as they give you a good solid hmmm…”, it’s a good fit. Bear sitting in a cubicle? Wait…

Another important rule of thumb for getting that solid “hmmm” out of people: the pictures “should be aesthetic and meaningful.” Not too meaningful, of course - you don’t want them to cross into the r/mildlyinteresting territory. Just like trusting your gut with spices when cooking, the same goes for capturing a “hmmm-worthy” contender. Plus, nobody will call you “an idiot sandwich” for mistaking a “hmmm” for the half-hearted “ahhh” the “mildly interesting” content is beloved for.

Another reason we believe people are drawn to the aesthetic absurdity that’s r/hmmm is the never-ending compulsion to look for meaning that simply isn’t there. We’re only but humans after all. And while reality makes progressively less and less sense as the years go by, with technological advances bringing us closer to surreal metaverses, people turn to equally ridiculous entertainment. As this writer for The Guardian once wrote: “One explanation for all this un-realism is that it’s a response to a world that has stopped making sense.” If only we could put it any better.

One way to understand the peculiar nature of out-of-context humor is to look at it through the perspective of memes - the internet’s beloved form of communal language. Although not every picture on the r/hmmm subreddit is a good fit for a meme, after every couple is one that’s the ideal canvas to become one. Just take a look at this genius Lara Croft cosplay. Or this person copying a crooked street sign down to a T.

“As internet culture has changed over the past few years, memes have become way less focused around wider stereotypes and identities and more nuanced and layered, often requiring a deeper level of understanding to get the joke,” Amanda Brennan, a trends expert at Tumblr, once explained for Forbes. And while there’s no right or wrong approach when it comes to “hmmm-generating” content, you can easily tell just by looking at this list that some images were instant hits compared to their counterparts.

In 2017, the Washington Post asked its readers “Why is millennial humor so weird?” It tried to find some much-needed answers by dissecting pop culture’s touchstones, such as Rick and Morty or BoJack Horseman. Part of the answer, it turns out, lies in classical staples of meaning - religion and family formation, for example - becoming less and less relevant as the generations go by. Does this help to understand why many of us find someone knitting a scarf out of ramen noodles “hmmm-worthy”? We doubt it. But at least we’re getting there.
