We've posted about the witty street art of UK urban artist Mobstr a while ago on Neatorama, but the punny gent has got a few new pieces, so it's worth revisiting. Here are 10 of the most sarcastically funny artwork he's done to date:

Something Like That

Do As I Tell You

Don't know your Double Windsor from your Pratt knots, but too embarrassed to buy clip ons? Knot a problem!

Maybe this Japanese necktie tying machine is for you. Take a look at how this clever little contraption loops and knots a tie before your very eyes. What an achievement, considering that there are 177,147 ways to tie a tie ...

I'll wait for the upgraded version which can surely do the Eldredge Knot (shown below):

Imgur user Bootlady went to the doctor's office the other day, and snapped this picture of the patient room.

'Twas probably her tenth or eleventh doctor (who? Yes!), and she was amused not only by the "Keep Calm I'm The Doctor" poster, but also this clever little sign below that says "You will obey and wash your hands!" (After all, how else would you EXTERMINATE all those germs?)

Funny, the room looks bigger on the inside. And I wonder what they keep in that little TARDIS lunch box?

And now for something completely different, here are some fascinating sculptures by Japanese artist Masao Kinoshita.

Kinoshita's bronze and painted resin sculptures feature the musculature and skeletal anatomies of various animals and mythical figures like the Hindu deity Ganesha and even a Kewpie doll. As you can see, the Tokyo University of Art and Design graduate combines technical mastery of sculpting buff bodies with a generous twist of the absurd.

Ever wonder where Gotham City was filmed? (Hint: not in New York) Hoth? Tatooine? Middle Earth? Or where the Kaiju Portal and SpongeBob's Bikini Bottom are supposed to be?

The folks behind Wondernode has created a map of supposed and filmed locations of fictional places in your favorite movies (shown in pieces here, but it really didn't do the original justice, so head on over to Wondernode to embiggen it to its original glory)

According to the map, Gotham City in the Batman trilogy is actually mostly Chicago. The forest moon of Endor was in the redwood forest of Northern California, and Waterworld was filmed in Hawaii.

A note about The Simpsons' Springfield: "Some labels are not fictional, and some are not places. Some locations, such as Bedrock and Nemo's anemone are educated guesses. Some places are just silly. Some, like Springfield are probably disputed, but if you research a bit you will hopefully come to the same conclusions as we did."

So, what kind of restaurant patron are you? The clever folks over at The Doghouse Diaries illustrated the difference amongst normal, picky, clever (bacon!), annoying restaurant patrons, and those who should just eat at home.

Me? I avoid all that awkward interaction between patron and waiter, and eat only buffets.

That little white plastic thingy that comes in your pizza box? Supposedly it's a device called the pizza saver, used to prevent the top of the box from collapsing at the center and ruining your pizza. That's what the pizza industrial complex said anyways.

We know better. All these years, pizza delivery companies have been shorting us the companion to that little pizza table: the mini pizza chair.

Parallel lines have so much in common. It's a shame that they'll never meet!

So. You've heard the lamentations of educators everywhere that regular people aren't interested in learning math. A lot of that is probably just marketing problem. How about if we add a little bit of romance novel-flair to math? Enter this clever little animated GIF above, found at The Meta Picture.

The looping GIF shows a few lessons from geometry:

Parallel lines that never meet

Asymptotes that get closer and closer but can never be together

Tangent lines that only meet once

and the clever tagline:

Math: We know drama

Science Ruined Dinosaurs by Mike Jacobsen, available over at the NeatoShop

First, dinosaurs had feathers like birds. And now, scientists found that they weren't even cold-blooded like the pre-historic reptilian monsters we thought they were.

Decades ago, scientists used to think that dinosaurs were cold-blooded animals, like lizards and crocodiles. Cold-blooded or ectothermic animals rely on the environment to regulate their body temperature. That's why they become sluggish in cold weather, and don't have to eat as much to grow (snakes, for example, can eat just one meal a month to stay alive). In contrast, warm-blooded or endothermic animals, like mammals, generate internal heat to regulate the body's internal temperature. Mammals can grow fast and remain active in cold weather, but constantly maintaining their body's internal temperature requires a lot of energy.

That view began to change in 1968, when a young paleontologist named Robert T. Bakker suggested that <a href="http://www.ucmp.berkeley.edu/diapsids/metabolism.html"> dinosaurs were "fast, agile, energetic creatures"</a>, much like the warm-blooded mammals of today.

Fast forward to today, when a new research study published in the journal Science reported that dinosaurs were neither cold-blooded nor warm-blooded. They were like the Goldilocks of biological thermoregulation, as suggested by John Grady, an ecologist at the University of New Mexico, and colleagues. "You know, if you are a little bit ... warmer-blooded than a reptile," Grady said, "essentially your muscles fire faster; your nerves fire faster; you are a more dangerous predator."

For his research, Grady noted that warm-blooded animals grow faster than cold-blooded ones. Using technique developed by paleontologist Greg Erickson to determine growth rates of dinosaurs by analyzing their fossils, Grady and colleague were able to calculate the metabolic rates of these prehistoric animals.

"Our results showed that dinosaurs had growth and metabolic rates that were actually not characteristic of warm-blooded or even cold-blooded organisms. They did not act like mammals or birds nor did they act like reptiles or fish," said co-author Brian Enquist of University of Arizona. "Instead, they had growth rates and metabolisms intermediate to warm-blooded and cold-blooded organisms of today. In short, they had physiologies that are not common in today's world."

Grady characterized dinosaurs as "mesotherms" and attributed that unique physiology to the reason that dinosaurs could grow to be much bigger than mammals. "It is doubtful that a lion the size of T. rex could eat enough to survive," he said.

Theatricality and deception, powerful agents to the decaffeinated.

Oh, so you think coffee is your drink? But you merely adopted the dark roast. I was born in it, molded by it. I didn't see other drinks until I was already a man, by then to me it was only decaffeination. Coffee betrays you because they belong to me.

You don't fear decaf ... you welcome it. Your libation must be more severe.

You have my permission to drink.

Vince Mancini over at Uproxx spotted Bane the Barista at a Starbucks dishing out libations to unsuspecting citizens of San Francisco. If you think that Starbucks butcher the spelling of your name on your cup of coffee, wait till this guy calls it out.

Summer is almost here (though from the hot, hot weather, it feels that it's already been here a while), so you know what this means, Neatoramanauts: it's BBQ time!

To help us celebrate, Kjetil Wold, Erik Heisholt, Jason Kinsella, Fredrik Melby and colleagues created this clever campaign for Norwegian grocery store chain Rimi called "Grillography." The typography features letters made from grilled meat, fish, fruit and vegetables.

The plumbing business ain't what it used to be, but thankfully, our pal Mario has found another line of work helping out firemen. Here's the Mario Fire Hydrant, located in downtown Harrisburg, Pennsylvania.

Quite a role reversal for our favorite plumber, who can power up to be Fire Mario. Oh, and we're still waiting for the Luigi Fire Hydrant, who can extinguish fire with his death stare.

Hydra is a fun little web diversion coded by graphic coder Nicolas Barradeu, who calls it a "generative shadow play." The idea is quite simple: drag your mouse to "slice" the shadow into two, then click on one part to re-spawn.

See how complex of a creature you can create. Here are a couple of mine:

Color me impressed: the United Arab Emirates Aerobatics Team "Al Fursan" (English "The Knights") painted the skies over Abu Dhabi with the country's Pan-Arab flag colors of black, white, green, and red.
