Dogs can't use their words to express their displeasure so they resort to visual and auditory clues like snarling, barking and growling to warn people and other animals that they're not okay.

And yet people don't seem to be picking up on these signals, so they're constantly getting bitten by dogs who just want to be left alone.

That "smile" on a dog's face when a stranger approaches them and tries to pet them without a proper introduction?

It may mean the dog wants to bite the stranger's hand for being such a pushy jerk, but most socialized dogs who have been raised around people resist the urge to snap.

Their wagging tail can also be misconstrued as a positive reaction to a person:

The tail can send a bunch of different emotional signals, depending on the kind of wag. For instance, look at the height of the tail -- if Spot is holding his tail up high, he's warning you.

If the tail is a little lower, he's more calm. If he's keeping it down near the "between the legs" position, he's scared.

Then you also have to consider the direction of the wag. A dog wagging its tail more to the right has noticed something it is cool with and would like to approach. However, if the wagging is switched to the left, it indicates anxiety. All of these nuances of wagging can convey a wide spectrum of different emotions to other dogs from a safe distance.

In the very near future mankind will use robots to effectively clean up all kinds of horrible messes so humans will no longer have to worry about being exposed to hazardous waste.

Before the robotic cleaning crews are mobilized we can see what it'll look like when a robot arm squeegees up a massive puddle of blood by viewing this installation by Sun Yuan and Peng Yu.

Even though full grown cats will act like kittens, and some may look like kittens their whole lives, it's easy to tell a kitten apart from a catdult- because kittens can't contain their frisky side.

(Image Link)

Some catdults start acting like kittens after hitting the catnip, but they come down from their high pretty quickly, while kittens keep going and going and going until their batteries run out.

(Image Link)

As we all know growing up can be a scary experience, and catdults look scary to a little kitten, so kittens should be encouraged to stay small and kitten-y for as long as possible.

When I started drinking liquor I was told by the supposed old hands of the whiskey world that the only difference between whisky and whiskey was the letter "E", but the truth runs much deeper.

The spelling actually reveals where the liquor was made- if it's spelled with an "E" then it was made in Ireland or the U.S., if it's spelled without an "E" then it was made in Canada, Japan or Scotland.

So if country of origin is important to you then check the spelling, but if you're just trying to bend your elbow with a bit of brown then forget about the spelling and drink up, because it's all good!

Coconut crabs are crazy cool looking, but they're also 3 feet long, weigh nine pounds and tear coconuts open with their claws, so if you see one in the wild it's probably best to keep your distance.

And even though you'll want to get a closer look despite knowing they can literally shred your skin you may want to reconsider- because they're also known as robber crabs, so they might snatch your shiny keys.

Coconut crabs are also extremely antisocial critters, living up to the "hermit" title better than most of their hermit crab cousins, so if you see a coconut crab waving at you it's trying to tell you to stay away!

Getting a bad haircut once meant wearing a hat until the hair grew back, or shaving it all off and starting over again, but nowadays victims like to share their haircut-astrophe online so their friends can laugh with them.

But sometimes a haircut is so bad people see it online and have to share it with their own social network, and next thing you know somebody's turning that cringeworthy haircut pic into a meme.

Memes that involve a bad haircut become part of the "say no more fam" meme family, where people imagine what the victim must have said to the barber to end up with such a terrible haircut.

Wolverine's most identifiable features are his claws which, along with his entire skeleton, have been coated in the virtually indestructible metal adamantium.

This advanced alloy is strong enough to stand up to a good smashing from an angry Hulk, so it's no surprise that an hydraulic press doesn't do much of anything against Wolvie's claws.

Still, there's something delightfully geeky about watching the press smash down on Wolvie's claws as they sink into the steel base like hot butter. (NSFW due to language)

This Hydraulic Press Channel video is a clever way to advertise the new Marvel movie Logan, which is in theaters March 3rd, and it's a good example of how to do an online promo the right way.

You've heard this tale many times before- a princess is bored of the royal life, so she decides to go out and find some adventure outside the castle walls, where dire circumstances in a dark forest help her grow up fast.

The animated short Dark Dark Woods is kinda like that, only in this story the dark woods come to the princess...

Dark Dark Woods was created by third year students from The Animation Workshop in Denmark, and hopefully it won't be long before this short is turned into a feature length movie!

Gas is still pretty expensive in most places, and air travel is full of ridiculous TSA delays, so train travel is starting to look pretty good to travelers who want to go places without hassles or headaches.

Riding the rails can be a relaxing and romantic way to see the country, as you travel down routes well over 100 years ago, and you can take an Amtrak train across the country for a mere $213.

Travel blogger Derek Low loves to travel by train, so he figured out a way to make the 3,400 mile long trip without breaking the bank via Amtrak's California Zephyr and Lake Shore Limited routes.

The trip takes 4 days without stopovers and takes you through Denver, Salt Lake City and Chicago, but if you want to see it all you can buy a 15 day pass for around $429 and stop all you like.

And if you can, Derek recommends riding in the Sightseer Lounge car, which features floor to ceiling windows and super comfy seating.

You could look through a small cabin window or sit in one of our observation cars. Your choice. #amtrak #adventure #500Destinations #travel @schoonmaker3

Wolverine will be a badass until the day he dies, and he'll probably spend his golden years slashing and slaying his foes like he did when he was a pup, but the Old Man Logan storyline tells a different story.

And if that wasn't confusing enough the new Marvel movie Logan tells yet another story about the mighty mutant's later years, so which story is to be believed?

This video by The Warp Zone seems like the most realistic interpretation to me!

People are constantly saying "they don't make them like they used to", a folksy statement that doesn't really apply to many things despite what the speaker had in mind.

But there is one thing they truly don't make like they used to- automobiles. The cars made in the early to mid-20th century were built to last a lifetime or more if properly cared for and driven safely.

Case in point- this 2011 video from the Milwaukee Journal Sentinel featuring Grace Braeger showing off her cherry 1957 Chevrolet, which is the first and only car Grace has ever bought.

Some people shouldn't be allowed to own a pet, and yet these bad owners keep adopting pets and abandoning them when caring for the animal becomes "too hard".

Rhino Lightning the Boxer fell victim to one of these bad owners when he was adopted from the Humane Society then returned months later because "They felt that he was a little too rambunctious with their small children".

But one of the kids clearly loved spending time with poor Rhino, and the helpful letter she sent along with Rhino shows she's going to be a great pet owner- unlike her parents.

Her adorable note contains advice like "Rhino need's lots of atenchen", "don't tease him with treats he will start to bark like crazy" and "his full name is Rhino litning then your last name. please don't rename him".

Rhino was adopted soon after being returned to the Humane Society of Utah, and the new owners agreed to follow the little girl's advice and let Rhino Lightning keep his awesome name.

The porcelain tchotchkes of the past were so boringly innocuous they felt out of place in a haunted house, dungeon or starbase, but these insectoid replicant figurines by Curious Cryptid Curios fit right in!

They were crafted by Miss Mantis to fit in with the rest of the snobbish porcelain statues on the shelf, but their heads reveal their true nature and make stuffy statue collectors recoil in horror.

Miss Mantis has also created an amazing series of Altered Authors, starring writers Louisa May Alcottontail, Jane Austern, Salmon Rushdie and the mysterious Neil Gaimantis.

There are far too many people out there who want to become professional artists and far too few with actual talent, so the wanna-bes resort to gimmicks to sell their art rather than earning their success.

But Norwegian artist Alexander Selvik Wengshoel wasn't trying to capitalize on a gimmick when he ate part of his own hip for an art project- he was just trying to make his art project that much more personal.

First, here's a little background on Alexander- he was born with a deformed hip, which was a constant source of pain and left him in a wheelchair for much of his life.

Around 2010 doctors offered him the chance to receive a metal hip replacement, which he jumped at so long as the doctors would let him film the operation and keep his old hip.

After some discussion the doctor agreed, and Alexander began The Body Project- the multimedia journaling of a life-changing event. So how did he end up eating his own hip?

Taking a piece of yourself home in a plastic bag is one thing. But how did you end up eating your own tissue?

Originally my meat wasn’t part of the project. I was just going to scrape it off and throw it away. As I gave the bone its first boil, in a little kettle, the flesh came off and I poured it into the wash sink. Then the shock hit me – I thought: "Oh my god, this is my flesh."

I quickly concluded that it was too personal to photograph and picked up a piece. I stared at it for a long time and then I said, "F@#k it." I put it into my mouth, tasted, chewed, swallowed and got to crying uncontrollably. It was happiness, anger and frustration combined.

Did you throw up?
No, after a couple of minutes of crying, it suddenly felt very natural and I didn’t think of it as human flesh anymore. So I continued boiling and scraping. Pulled out some chilli and garlic and fried it in a pan. Salt and pepper was mandatory and so was a good bottle of wine. Then I lit some candles and also whipped up some potato gratin. Sat down and ate it all – it became a ceremony, a ritual.
